低温循环CFRP飞机翼尖小翼性能研究

本文针对飞机反复起降的低温循环环境对CFRP翼尖小翼悬臂弯曲性能的影响,利用理论推导和力学试验方法探究并证实了低温循环对CFRP飞机翼尖小翼抗悬臂弯曲性能的削弱作用,为CFRP复合材料在低温循环下的性能研究提供参考。

This paper aims at the influence of low-temperature cycle environment of aircraft repeated take-off and landing on the bending performance of CFRP wingletcantilever,the weakening effect of low-temperature cycle on the cantilever bending performance of CFRP winglet is explored and confirmed by theoretical derivation and mechanical test methods,which provides a reference for the performance research of CFRP composite materials under low-temperature cycle.
