  • Description of Anomalous Water Absorption Behaviour of Woven Glass
           Reinforced Cyanate Ester Composites

    • Abstract: Description of Anomalous Water Absorption Behaviour of Woven Glass Reinforced Cyanate Ester Composites
      Pages 92-106
      Author Panagiota KelverkloglouEvgenia KolliaAntonis VavouliotisVassilis Kostopoulo
      This work studies the water absorption behaviour of woven glass fibre reinforced cyanate ester composites used in the plenum of the air conditioning pack of aircraft's environmental control system. For absorption tests, samples were immersed in distilled water baths at four different temperatures: 40°C, 60°C, 75°C and 90°C. In general, the composites have shown strong non-Fickian behaviour. The progression of mass absorption is described analytically using a combination of Fickian diffusion and relaxation process. Thus for the temperatures of 40°C, 60°C and 75°C a dual stage model was used. At 90°C the material exhibits extreme non-Fickian behaviour due to chemical ageing procedures which cannot be accurately modeled. From the mass control analysis, lots of information is provided for the correlation between the temperature and the diffusion coefficient or the start of the moisture equilibrium. Also, the regions of physical and chemical ageing can be clearly distinguished, giving a good profile of the material behaviour at elevated temperature. The dual stage model that is proposed precisely describes the behaviour of these materials at different temperatures up to 75°C. The chemical ageing that is taking place at 90°C creates another profile that should be investigated in a more detailed level than macro-scale.

  • Mechanical and Optical Properties of Eu(TTA)3phen and UV-stabilizer Doped
           LDPE Film under Natural Weathering Condition

    • Abstract: Mechanical and Optical Properties of Eu(TTA)3phen and UV-stabilizer Doped LDPE Film under Natural Weathering Condition
      Pages 86-91

      Low-density Polyethylene films doped with 0.1 % Eu(TTA)3phen with and without the addition of 0.1% UV-stabilizer were hot-blown by a lab scale extrusion process. The average thickness of the films was 100 µm and was exposed under natural weathering conditions for 1,000 hours to evaluate their optical and mechanical properties. A commercial agriculture film with the same average thickness under the same exposure and conditions was used as reference. Mechanical properties of the films before and after the exposure were measured according to ASTM D882 standards. The optical and chemical properties were characterized by spectrofluorometer and FTIR. Mechanical tests showed that tensile strength (TS) and elongation at break (EB) of the doped films in machine direction (MD) orientation decreased after the exposure, but still comparable to commercial films. All emission transition lines of Eu3+ ions for doped films were observed when excited at 394 nm whilst the highest peak was detected at 612 nm. The highest peak intensity of LDPE doped Eu(TTA)3phen without UV-stabilizer dropped by 90% after the exposure. These results indicated that incorporation of UV-stabilizer has prolonged and increase the ability of the films to endure photo degradation effects, offering improved greenhouse plastic films.

  • Preparation of Functional Xanthan Gum Materials Using Ionic Liquid

    • Abstract: Preparation of Functional Xanthan Gum Materials Using Ionic Liquid
      Pages 63-72
      Author Keisho IimoriKazuya YamamotoJun-ichi Kadokaw
      Natural polysaccharides are important organic substances and expected to incorporate in functional materials. Xanthan gum, which is a water soluble polysaccharide produced by Xanthomonas campestris, is a useful food hydrocolloid. In this review article, the preparation of functional xanthan gum materials using an ionic liquid, 1-butyl-3-methylimidazolium chloride (BMIMCl), is presented. Xanthan gum forms ion gels with BMIMCl by the simple and efficient procedure, which are further converted into hydrogels. These gels showed good mechanical properties, and interesting functions. The composite and binary hydrogels and films of xanthan gum with hydroxyapatite and cellulose are also fabricated through the ion gel formation. The partially carboxylated xanthan gum nanoparticles are obtained by regeneration from the solution in BMIMCl using ethanol. Derivatization and modification of xanthan gum are also conducted by appropriate procedures.

  • Synthesis of Pendant Amine Functional Methyl Acrylate/Acrylonitrile
           Copolymers and Reactively Compatibilized Blends with Poly(Ethylene)

    • Abstract: Synthesis of Pendant Amine Functional Methyl Acrylate/Acrylonitrile Copolymers and Reactively Compatibilized Blends with Poly(Ethylene)
      Pages 73-85
      Author Khadija IqbalBrenden MouenMilan Mari
      Acrylonitrile (AN)-containing copolymers have not been widely considered as barrier dispersed phases in blends with poly(ethylene) (PE), despite the versatility in their synthesis (i.e. controlled radical radical polymerization). To use such copolymers in PE, compatibilization is essential to obtain the desired morphology and thus we made a primary amine functional monomer, IDBA (3-isopropenyl-α,α–dimethylbenzylamine), with minimal purification steps, high yield (up to 76%) and high conversion (98%) in multi-gram batches from a cheap, commercially available precursor m-TMI (3-isopropenyl-α,α−dimethylbenzyl isocyanate). Terpolymers of AN, IDBA, MA (methyl acrylate) and AN (acrylonitrile) were then synthesized in DMF solution by conventional radical polymerization (number average molecular weight = 26 – 28 kg mol-1). These polymers are reactively blended with maleic anhydride grafted PE(PE-MAn) at 20 and 40 wt% loadings at 140 °C and compared with non-reactive PE-MAn/MA-AN-AMS (AMS = –methyl styrene). Scanning electron microscopy (SEM) indicates smaller, sub-micron, thermally stable dispersed phase particle size (volume to surface area diameter 〈D〉VS) for the reactive blend (〈D〉VS = 0.6 μm). The reactive blending of the high-AN containing terpolymers with PE is thus promising as a barrier material agains hydrocarbons.

  • Predictive Model for Tensile Properties of Carbon Fiber-Reinforced
           Polymers at Various Moisture Contents

    • Abstract: Predictive Model for Tensile Properties of Carbon Fiber-Reinforced Polymers at Various Moisture Contents
      Pages 53-62
      Author Yi Di BoonSunil Chandrakant Josh
      A model to estimate the tensile properties of carbon fiber-reinforced polymers (CFRP) based on their moisture contents and molecular structures is formulated and studied. In the proposed model, water molecules absorbed by polymers are considered congregated near the sub-micro-cavities within the polymers. The absorbed water molecules form hydrogen bonds with the polymer molecules and cause the regions around the sub-micro-cavities to have a reduced elastic modulus. The additive group contributions for polymers are used to determine the contributions of hydrophobic and hydrophilic functional groups separately. This enables the effects of water molecules on the mechanical properties of polymers to be quantified and estimated. For CFRP laminae, an additional effect of moisture on the fiber-matrix interface is considered in the calculation of the transverse tensile strength. The tensile properties are calculated using the proposed model agreed well with the experimental values. It is expected that the time and materials required to obtain the mechanical properties of CFRP exposed to humid environments can be reduced with the help of this model.

  • Component Ratio Effect of Melamine Cyanurate/Magnesium Hydroxide on the
           Flame-retardant Properties of Ethylene-Propylene-diene Terpolymer Rubber

    • Abstract: Component Ratio Effect of Melamine Cyanurate/Magnesium Hydroxide on the Flame-retardant Properties of Ethylene-Propylene-diene Terpolymer Rubber
      Pages 33-40
      Author Zhongfeng TangYoushuang ChenFeng TianHaitao LinZengfang Zhan
      A synergistic flame-retardant compound containing magnesium hydroxide (MH) and melamine cyanurate (MCA) ingredients was prepared with ethylene-propylene-diene monomer (EPDM) composite to find a highly efficient, halogen-free, and phosphorus-free flame retardant. The flame-retardant MH/MCA compound particles were modified by a silane coupling agent to increase surface activity. Two series of EPDM/MH/MCA composites were prepared by direct blending methods. The mechanical and flame-retardant properties of the composites were investigated by various methods. The Rockwell hardness and tensile strength of EPDM/MH/MCA composites significantly increased after adding MH/MCA compound particles compared with EPDM composites. Results showed that incorporating MH/MCA compound particles evidently improved the flame-retardant and mechanical properties of EPDM. Both of these properties increased, and the flame-retardant properties of the materials met the UL94 V-1 requirements. The excellent properties of the composites were obtained after adding 40 phr MH and 20 phr MCA with a silicane coupling agent. Results indicated that the EPDM/MH/MCA composite with the appropriate MH/MCA mass ratio had the highest LOI, UL94 V-0 rating, lowest heat release rate, and highest residue yield. These results implied that the appropriate MH/MCA mass ratio formed a better flame-retardant system and adequately exerted their synergistic effects. Different flame-retardant performances should be attributed to their own characteristics, dispersion state in EPDM matrix, and the change of structure during burning.

  • Electrical Conductive Surface Functionalization of Polycarbonate Parts
           with CNT Composite Films during Injection Molding

    • Abstract: Electrical Conductive Surface Functionalization of Polycarbonate Parts with CNT Composite Films during Injection Molding
      Pages 41-52
      Author Felix KroschwaldMichael Thomas MüllerPetra PötschkeJürgen NagelGert Heinric
      This study describes a reactive process to transfer an electrical conductive polycarbonate (PC) film onto the surface of bulk polycarbonate by an injection molding process using hyper branched poly (ethylenimine) (PEI). Due to a nucleophilic substitution reaction between the amino groups of the poly (ethylenimine) and the carbonate groups of the PC, a stable covalent crosslinking is established. The resulting conductive layer has an average thickness of about 3 -7 µm and a surface roughness that depends on the roughness of the cavity. The lowest resulting electrical surface resistivity of the final injection molded part of 5.58 ∙ 104 Ω per square is measured for a composites film loaded with 5 wt.% CNT . The crosslinking PEI layer has a thickness of about 50 nm, which equates with the hydrodynamic radius of a random PEI molecule with molecular weight of about 750.000 g∙mol-1. As a consequence, all PEI intermediate surface films remain completely on the PC parts.

  • Cutting Mechanism of Drilling CFRP Laminates—Effect of Ultrasonic
           Torsional Mode Vibration Cutting

    • Abstract: Cutting Mechanism of Drilling CFRP Laminates—Effect of Ultrasonic Torsional Mode Vibration Cutting
      Pages 1-10
      Author Hukuzo YAGISHIT
      Cutting mechanism of drilling CFRP laminates and effects of ultrasonic torsional mode vibration cutting are investigated. CFRP laminates are made of carbon fiber reinforced/epoxy-resin matrix composite ply. Challenges in drilling CFRP laminates arise because of anisotropy due to carbon fiber orientation and heterogeneousness between carbon fiber and epoxy-resin. Experimental works are performed to characterize major hole quality parameters and cutting mechanism encountered when conventional drilling CFRP laminates. Some craters of about 100 μm depth are found at the particular position on inner surface of drilled hole and the mechanism for the crater to be generated is revealed based on cutting mechanism of both anisotropic and hheterogeneous composite material. In order to improve hole quality and tool life, the specific drilling assisted by ultrasonic torsional mode vibration of 27 kHz is examined. The ultrasonic torsional mode vibration cutting is considerably effective to restrain the generation of crater and also to elongate tool life about five times.

  • A Review on the Application of Nucleation Theories in Thermoplastic Foams

    • Abstract: A Review on the Application of Nucleation Theories in Thermoplastic Foams
      Pages 11-32
      Author Mozaffar Mokhtari Motameni ShirvanMohammad Hossein Navid FamiliAtefeh Golban
      The physical foaming agent is dissolved in the polymer at a pressure and temperature beyond its critical condition and the foam structure is formed by a sudden pressure drop or a temperature increase in the mixture in three steps; nucleation, growth and coalescence. In the nucleation step, due to a supersaturation, thermodynamic unstability is formed in the mixture. This induces a tendency in the solvent molecules for a phase transition from a supersaturated state to a gas state in the direction of unstability reduction. By overcoming the energy barrier, the free energy of the system is reduced and gas stable nucleuses are formed in the free volumes of the polymer chains. Growth and coalescence of the nucleuses take place with the diffusion of the gas molecules inside them. With increase in the nucleation efficiency, the growth and coalescence rate are reduced. Therefore, prediction of nucleation rate is an important factor for controlling the thermoplastic foam structures. Investigation of the nucleation step has been doable with the aid of nucleation theories. The classical nucleation theory is a prominent method for the investigation of nucleation phenomena in thermoplastic foams, but due to the existing of a divergence between its theoretical values with the experimental data, some modifications have been introduced into this theory. Other competing theories such as the Density Functional Theory and the Self Consistent Field Theory have also been developed. The main aim of this review paper is investigation of the existing theories and their modifications for thermoplastic foams.
