摘要

摘要: 以碳纖維2.5D淺交彎聯結構為預制體,分別采用樹脂傳遞成型工藝(RTM)和熱壓成型工藝(HPM)制備了碳纖維增強酚醛樹脂基摩擦材料.通過MS-T3001摩擦磨損試驗機考核了材料的摩擦磨損性能,采用掃描電子顯微鏡、激光三維形貌掃描儀觀測了材料的磨損形貌,對比分析了兩種成型工藝對材料摩擦學性能的影響.結果表明:隨著滑動速度和工作載荷的增大,材料的摩擦系數均減小.熱壓成型工藝成型摩擦材料的主要磨損形式為磨粒磨損,摩擦系數0.085~0.130,磨損率1.5×10^-8 g·N^-1·m^-1.樹脂傳遞成型工藝成型摩擦材料的主要磨損形式為黏著磨損和疲勞磨損,摩擦系數0.075~0.120,磨損率7.5×10^-8 g·N^-1·m^-1.

Abstract: Resin transfer molding (RTM) and hot-pressing molding (HPM) were used to prepare phenolic resin matrix composites reinforced by carbon fiber. The tribological properties of the materials were tested using a MS-T3001-type friction and wear tester. A scanning electron microscopy and three-dimensional laser microscopy were used to analyze the superficial microstructure of the friction materials. Furthermore, a comparative analysis was employed to investigate the influences on the tribological properties by two types of material-forming processes. Results indicate that the friction coefficient decreases with increased relative sliding speed and workload. For the RTM friction material, the main form of wear is adhesive wear and fatigue wear, the coefficient of friction is 0.075-0.120, and the wear rate is 7.5×10^-8 g·N^-1·m^-1. In contrast, for the HPM friction material, abrasive wear is the main form of wear, and the friction coefficient and wear rate are 0.085-0.130 and 1.5×10^-8 g·N^-1·m^-1, respectively.
