碳纤维具有质地柔软、热稳定性好、耐腐蚀、尺寸稳定性好、比强度、比刚度高等优良特性,因而它是宇航飞行器应用的最有希望的工程材料之一。 我们可以用选择增强材料的品种(即纤维种类)和铺层方向来满足结构材料的设计要求。由于影响碳-环氧复合材料性能的因素很多,本文只对在固定基体成份为环氧648+BF_3·MEA情况下的纤维状态对碳-环氧复合材料性能的影响进行讨论。以便对碳-环氧复合材料进行进一步的研究和应用。
Carbon fiber has the characteristics of soft texture, good thermal stability, corrosion resistance, good dimensional stability, specific strength and high rigidity, so it is one of the most promising engineering materials for spacecraft applications. We can meet the design requirements for structural materials by choosing the type of reinforcing material (ie, the type of fiber) and the orientation of the layup. Due to many factors affecting the performance of carbon-epoxy composites, this paper only discusses the influence of the fiber state on the properties of carbon-epoxy composites with epoxy matrix 648 + BF_3 · MEA. In order to further research and application of carbon-epoxy composites.
