摘要
目前在耐高温树脂中能经受长期高温氧化的热固性树脂只有聚酰亚胺 ,作为耐高温树脂基体及其复合材料 ,本文研究了CF/聚酰亚胺复合材料在不同温度的力学性能和热性能。作为应用量大面广的树脂基体及其复合材料 ,本文研究了两种环氧基体及其CF/环氧复合材料和GF/环氧复合材料在不同温度的力学性能。研究结果表明 ,复合材料的耐热性主要取决于基体。基体耐热性高的 ,复合材料在高温也保持高强度。
So far, the polyimide is the only thermosetting resin that can resist high-temperature oxidation for a long period of time. This paper presents the mechanics and thermal properties of the CF/ polyimide composite in different temperature. As the widely used resin matrix and composites, two kinds of epoxy matrix and its CF/epoxy composite and GF/composite have different mechanics property under different temperature. The result shows that the thermal property of the composite mainly depends on the matrix. If the matrix can resist high temperature, its composite can also have high strength under high temperature.
