摘要
以三种不同环氧树脂体系(TDE-85,F-51,E-51)为基体,以相同体积分数的短碳纤维和玻璃纤维为增强材料,制得了树脂基短纤维复合材料(SFRP)。应用混合定律和Halpin-Tsai方程对其力学性能进行分析,应用扫描电镜对其冲击断面的形貌进行分析。结果表明,树脂基体所含官能团、树脂基体固化后的特性以及增强纤维的表面性质是影响SFRP力学性能的重要因素。
Taking 3 varieties of different epoxy resins （TDE-85, F-51, E-51） as matrices, same volume fraction （5%） of short carbon and glass fiber as reinforcing materials, short fiber reinforced polymers （SFRP） were prepared in this paper. The mechanical properties and morphology of the SFRP were analyzed by means of mixing rule and Halpin-Tsai equation, the impact fracture surface of the SFRP was studied by means of SEM. The results showed the mechanical properties of the SFRP were strongly affected by the functional group of the epoxy resin, the characters of cured matrices and the properties of the fiber surface.
