Kinetics of moisture sorption and improved tribological performance of keratinous fiber-reinforced ortho-phthalic polyester biocomposites

ABSTRACT

This paper presents the influence of randomly oriented bovine hair fibres on the kinetics of moisture sorption and abrasive wear resistance of unsaturated polyester. The investigated properties were studied dependent on predetermined volume fractions of hair fibres in polyester matrix. Test samples were developed according to appropriate test standards and subjected to preferred characterizations. It was found that a linear relationship exists between water absorption and fibre volume fraction of biocomposites. The biocomposites exhibited Non-Fickian, Case II, and Super Case II Kinetics in correlation with diffusion mechanisms. Also, improved resistance to abrasion of the biocomposites was independent of fibre volume fraction. Overall, the biocomposites evinced better anti-abrasion properties than the monolithic polymer and carbon was revealed as the principal element in the hair fibre.

摘要

本文研究了随机取向的牛毛纤维对不饱和聚酯的吸湿性和耐磨性的影响。研究了聚酯基体中头发纤维的预定体积分数对其性能的影响。根据适当的测试标准开发测试样品，并进行优选表征。结果表明，生物复合材料吸水率与纤维体积分数呈线性关系。生物复合材料具有Non-Fickian案例II与扩散机制相关的超级案例二动力学。此外，生物复合材料耐磨性的提高与纤维体积分数无关。总的来说，生物复合材料显示了更好的抗磨损性能比单片聚合物和碳被发现在头发纤维的主要元素。
