中文摘要:
      目的 分析不同试验条件下碳纤维增强尼龙复合材料的性能变化规律， 获得该种材料在高温和低温条件下的老化特征。方法 对制备的碳纤维增强尼龙复合材料拉伸样和缺口冲击样， 开展高温和低温试验， 定期测试其拉伸、 冲击性能， 分析各试验条件下力学性能的变化趋势， 总结该材料的老化特征。结果 几种试验条件下均未造成该材料外观损伤， 冲击强度出现了前期升高后期降低的变化趋势， 而拉伸强度前期略微降低， 随着试验进行逐渐升高。结论 碳纤维增强尼龙复合材料在高温和低温条件下无明显的外观老化特征， 而力学性能在高温16天后材料会呈现出较缓慢的热老化趋势。
英文摘要:
      Objective To obtain the aging characteristics of carbon fiber reinforced nylon composites in both high and low temperature test conditions by analyzing its variation regularities of the mechanics properties under different test conditions. Methods High-temperature and low-temperature experiments were conducted to the carbon fiber reinforced Nylon composites with tensile and notched impact specimens and their tensile strength and notched impact properties were periodically tested. The change regularities of their mechanics properties were analyzed under different test conditions and then the aging characteristics of that kind of material was summarized. Results The appearance of material was not damaged under the test conditions. The impact strength showed the tendency of rising at the earlier stage and lowering at the latter stage. The tensile strength reduced a little bit at the earlier stage and then enhanced gradually. Conclusion Carbon fiber reinforced nylon composites had no visible characteristics of appearance aging in both high and low temperature tests. The mechanics property of the material presented the tendency of relatively slow thermal aging after 16 days of high-temperature test.
