| 摘 要： | 文章研究了原子氧辐照下gf/pi和nano-tio2/gf/pi复合材料的摩擦学性能,结合结构分析探讨了原子氧辐照对其摩擦学性能的影响机理.研究发现原子氧辐照能够破坏复合材料表面的树脂基体分子链,引起复合材料表面结构发生变化.原子氧辐照对pi复合材料的摩擦系数影响不大,但有使其磨损率降低的趋势,这可以归因于复合材料表面化学结构和组成的变化对对偶钢环上的转移膜所产生的影响.

| Abstract: | The tribological properties of GF/PI and nano-TiO2/GF/PI composites irradiated by atomic oxygen are studied in this paper.The influencing mechanism of atomic oxygen irradiation is discussed,and the structural analysis of the composite surface is carried out before and after the irradiation.It is found that atomic oxygen irradiation could destroy the matrix molecular chains in the composite surface,and change the surface structure of the composite.The friction coefficient of the PI composite is little influe... |
