摘要
采用万能材料试验机、水压爆破试验对两种不同纺丝工艺的T800级炭纤维在缠绕浸渍过程中的耐磨性及φ150 mm容器性能进行了系统研究,并对φ150 mm容器缠绕层应力分布进行了对比分析。结果表明,由干喷湿纺T800SC炭纤维缠绕制备的φ150 mm容器性能优于湿法纺丝T800HB炭纤维。这主要是由于相比T800HB炭纤维,T800SC炭纤维在缠绕过程中不易磨损,可保持其纤维强度。因此,T800SC炭纤维具有更佳的缠绕适配性,更适合作为固体火箭发动机复合材料壳体的增强体。此外,由于T800HB炭纤维复合材料容器的封头靠近赤道位置处产生压缩应变较大,易在该位置发生复杂的破坏模式。因此,需采用较小的应力平衡系数进行容器设计。
The anti-wear properties during the dipping process andφ150 mm vessels properties of T800 carbon fibers by two different spinning processes were studied by universal tester and hydraulic burst test,and the stress distribution in winding layer ofφ150 mm vessels were also analyzed.Results showed that the property ofφ150 mm vessel wound with dry jet-wetting spinning T800 SC carbon fiber was much better than that of wetting spinning T800 HB carbon fiber.This could be explained that compared with T800 HB carbon fiber,it was difficult to wear for T800 SC carbon fiber during winding process,leading to the high retention of strength.Therefore,T800 SC carbon fiber possessed better winding adaptability,and was more suitable for the reinforcement of solid rocket motor composite case.Besides,its compressive strain produced on the location near equator of vessel head was larger,resulting in the susceptibility of complex destruction around this location,therefore smaller stress balance coefficient need to be used to design the vessel.
