摘要
三维机织预成型体具有良好的层间力学性能、结构稳定性和可设计性,可实现多层整体织造,满足高厚一体化的使用要求,已在航天器天线罩性能测试用随炉试样、战术导弹空气舵等结构功能一体化部件上应用。目前,随着我国武器型号的升级换代和更高的性能要求,对其面内±45°方向和经向力学性能提出了进一步强化的指标要求。对几种典型角联锁机织结构及其力学性能做了对比分析,研究了其发展现状,为多层角联锁机织预成型体的应用研究提供理论参考。
3 D woven preforms had good interlaminar mechanical properties,structural stability and designability.It could realize multi-layer integral weaving and meet the application requirements of high thickness integration.It had been applied to the structural and functional integration components such as furnace-mounted samples for performance test of space weapon radome and tactical missile air rudder.At present,with the upgrading and higher performance requirements of weapon models in China,the mechanical properties in the in-plane 45 direction and the warp direction were required to be further strengthened.Therefore,several typical angle interlocking woven structures and their mechanical properties were analyzed,and their development status was studied,which provided theoretical guidance for the application research of multi-layer angle interlocking woven preforms.
