石墨纤维是在航天/航空、军工等高技术领域中使用效果最好的复合材料的增强纤维,其耐热氧化性决定了石墨纤维复合材料的高温使用价值。虽然基体树脂可将纤维与环境隔开,但时间久了空气仍能从树脂及纤维和树脂的交界处渗入,并与纤维接触,特别是在纤维和基体的复合效果不好和有空隙的情况下,气体可以很快地穿过交界区渗入材料中。因此,如果用不稳定的增强材料和稳定的树脂结合,制成的层压复合材料的稳定性将大大低于树脂本身。要使石墨纤维复合材料在
Graphite fiber is the most effective composite material used in aerospace / aviation, military and other high-tech fields. Its resistance to thermal oxidation determines the high temperature use value of graphite fiber composite material. Although the matrix resin separates the fibers from the environment, air can still penetrate from the resin and the interface between the fibers and the resin over time, and come in contact with the fibers, especially when the composite effect between the fibers and the matrix is poor and there are gaps Under the gas can quickly penetrate the border zone into the material. Therefore, the stability of the resulting laminated composite will be much lower than if the resin is stabilized with an unstable reinforcing material. To make graphite fiber composite material in
