Abstract:

在对纤维缠绕复合材料缠绕图案分析的基础上,考虑到纤维束的交叠与波动,提出一种用于计算纤维缠绕复合材料弹性模量的方法。该方法是在纤维缠绕图案中提取一代表单元,将代表单元分成层板区域和纤维束波动区域。层板区域用经典层板理论计算弹性模量;纤维束波动区域根据纤维波动的细观图形及走势计算弹性模量。根据层板区域和纤维束波动区域在代表单元中所占的比例,组合2个区域的弹性模量以获得代表单元的总体弹性模量。通过测试炭纤维/环氧树脂缠绕管在轴向拉伸载荷下的轴向弹性模量及泊松比,验证了理论计算结果,表明该计算方法能较准确地计算纤维缠绕复合材料的弹性模量,因此可为这类材料的设计计算提供有益的理论依据。
