摘　　要：本文对两种铺层的矩形、三角形正交非对称铺层的碳纤维板双稳态壳成型后的几何外形及性能进行了研究,通过制备两种实验模型完成双稳态成型实验,并利用有限元软件ABAQUS模拟了从平面结构冷却固化为具有双稳态特性壳结构的过程,与两种铺层双稳态壳结构的实验外形结果进行了对比分析,两者的最大面外位移相差不大。In this paper, the bi-stable geometric shapeof rectangular and triangular unsymmetric cross-ply laminates were studied. The finite element software ABAQUS was used to simulate the process from a plate to a bi-stable shell.The experimental results of two types of bi-stable laminates shell werecompared with the finite element simulation results.There is little difference in the maximum out-of-plane displacement between these two results.
