In the present work, the effect of pre-strain and number of shape memory alloys on the compressive performance of glass/epoxy composite conical shells were studied. The filament-winding process was applied to manufacture the composite specimens, without and with 1 and 2 SMA wires of 0, 1, 2 and 4% pre-strain. Based on the results of the axial compression tests, the maximum stiffness was obtained in the specimen with no SMA wires. Besides, the specimen with 1 SMA wire and 4% pre-strain exhibited the highest level of the compressive load-bearing capacity, which is attributed to the transformation of austenite to twinned martensite (shape memory effect) due to the higher value of pre-strain. Finally, scanning electron microscopy was conducted, and it was found to be consistent with the results of the compression tests on the specimens.

在目前的工作中，研究了预应变和形状记忆合金的数量对玻璃/环氧树脂复合圆锥壳抗压性能的影响。应用长丝缠绕工艺来制造复合材料样本，该复合材料样本不带和带有预应变分别为0％，1、2％和4％的1条和2条SMA线。根据轴向压缩测试的结果，在没有SMA线的样品中获得了最大刚度。此外，具有1条SMA线和4％预应变的试样表现出最高水平的压缩承载力，这归因于奥氏体向孪晶马氏体的转变（形状记忆效应），这是因为预应力值较高。应变。最后，进行了扫描电子显微镜检查，发现与样品的压缩试验结果一致。
