Investigating the Effects of Operational Factors on Wear Properties of Heat-Treated Pultruded Kenaf Fiber-Reinforced Polyester Composites using Taguchi Method

ABSTRACT

This study investigated the mechanical and wear properties of heat-treated pultruded kenaf fiber-reinforced polyester composites (PKFPCs) using pultrusion technique. A total of three heat treatment temperatures (120, 140, and 170°C) of PKFPC and untreated PKFPC were produced and their performance was compared. Different sliding conditions and different heat treatment temperatures on PKFPC were tested according to the Taguchi orthogonal array design of experiment. The worn surfaces and transfer films produced were examined using scanning electron microscopy. The results showed that PKFPC with a 140°C heat treatment exhibited better wear performance than untreated PKFPC and PKFPC with 120 and 170°C heat treatments. The flexural strength and modulus of PKFPC increased after heat treatment. The counterface roughness and heat treatment temperature are the most significant factors affecting the wear performance of PKFPC. The optimum sliding conditions to achieve lowest wear and friction in the tested operating environment were determined.

摘要

本研究调查的力学和热处理红麻纤维增强聚酯复合材料的磨损性能拉挤(PKFPC)采用拉挤成型工艺。共有三个热处理温度(120°C、140 C和170 C°°)和未经处理的PKFPC制作和比较它们的性能。不同的滑动条件和不同热处理温度对PKFPC根据田口正交实验设计(DOE)测试。用扫描电子显微镜(SEM)对磨损表面和转移膜进行了观察。结果表明， PKFPC与140°C热处理具有更好的耐磨性能比未经处理的PKFPC和120°PKFPC C、170 C热处理°。热处理后的弯曲强度和模量增加，表面粗糙度和PKFPC，热处理温度是影响pkfpc磨损性能的最重要的因素，确定了最佳的滑动条件在测试运行环境达到最低的磨损和摩擦。
