摘要
采用不对称铺层复合材料对直升机等飞行器的结构减重具有重要意义。本文对不对称铺层复合材料层压板的变形控制方法进行了初步研究,通过调整固化工艺参数和采用反变形模具来减小变形量。研究表明,通过降低固化温度可以在一定程度上减小变形量,采用反变形模具可以较有效地控制不对称层压板变形,但可能会带来扭曲等问题,其适用范围尚需进行进一步的研究。
Using unsymmetric composite laminates are benefit to reducing the structure weight of some aircrafts such as helicopter.In this paper,we aim at the control methods of the warpage of the unsymmetrical composite laminates.The method used in our study included adjusting the curing parameters and using the anti-warpage mould.The results of the experiment indicate that reducing curing temperature can reduce the warpage.Using the anti-warpage mould is an effective method of controlling the warpage,but it could ca...
