摘要
研究了碳纤维增强聚对苯二甲酸乙二醇酯(PET/CF)复合材料在不同应变率及温度条件下的拉伸性能及损伤模式,拉伸应变率从0.001 s^(-1)至50 s^(-1),温度从-40℃至80℃。结果表明,随着应变率的增加,复合材料的弹性模量、拉伸强度均有所提高;随温度的升高,其弹性模量、拉伸强度均降低,而失效应变逐渐增大,表现出较强的应变率及温度敏感性。
The tensile behavior of carbon fiber reinforced poly(ethylene terephthalate) was studied at strain rates from 0. 001 s-1 to 50 s-1 and temperatures from -40 ℃ to 80 ℃. The tensile strength increased with increasing strain rate, and decreased with increasing temperature. In contrast, the failure strain increased with increasing temperature.
