摘要

采用注塑成型技术,开发了基于聚甲醛共聚物(POM C)、10 wt.% 玻璃纤维(GF)和 1、3 和 5 wt.% 石墨(Grt)填料的独特混合热塑性复合材料。根据田口 L16 正交阵列,进行了本实验,目的是确定在一系列载荷(即 5、10、20 和 30 牛顿)、滑动速度(即 200、400、600 和 800 转/分钟)和运行时间(即 15、30、45 和 60 分钟)下的摩擦系数(COF)和特定磨损率(SWR),并在整个实验过程中改变 Grt 的重量百分比(即 1、3 和 5 重量百分比)。方差分析(ANOVA)用于评估影响输出功能(即 COF 和 SWR)的最重要因素。研究结果表明,加入 Grt 后,POM C/10GF 复合材料的三重力学性能、结构性能和热性能都得到了显著改善。此外,还采用了各种显微镜方法来研究复合材料的磨损机理和磨损样品的表面形态。含有 3 wt.% Grt 的 POM C/10GF 由于增强了界面粘合特性而表现出优异的摩擦学特性,从而提高了耐磨性。

Impact of graphite on tribo-mechanical, structural, and thermal behaviors of polyoxymethylene copolymer/glass fiber hybrid composites via Taguchi optimization
Unique hybrid thermoplastic composites based on polyoxymethylene copolymer (POM C), 10 wt.% glass fiber (GF) and graphite (Grt) filler at 1, 3, and 5 wt.% were developed using injection molding technique. According to the Taguchi L16 orthogonal array, present experiments were carried out with the aim of determining the coefficient of friction (COF) and specific wear rate (SWR) under a range of loads (namely, 5, 10, 20, and 30 N), sliding speeds (namely, 200, 400, 600, and 800 rpm), and run times (namely, 15, 30, 45, and 60 min) with varying wt.% of Grt (namely, 1, 3, and 5 wt.%) throughout the experiment. Analysis of variance (ANOVA) was used to evaluate the most significant factors that affect the output functions (viz., COF and SWR). The findings demonstrated that POM C/10GF composites' tribo-mechanical, structural, and thermal properties were considerably improved upon by including Grt. Various microscopical methods were also employed to study the wear mechanisms of the composites and the surface morphology of the worn samples. The POM C/10GF with a 3 wt.% of Grt exhibited superior tribological properties owing to its enhanced interfacial bonding characteristics, resulting to increased wear resistance.
