近年来，变角拖曳技术的发展由于其强大的结构剪裁潜力而引起越来越多的关注。然而，可变角丝束层合板的失效机制的全部细节尚未可知，并且设计的复杂性也需要使用数值分析和新技术的可变角丝束复合材料。本文讨论了设计中使用变角度纤维层合板的两个主要问题。首先，建立了一个数学模型，建立了一个三维可变角度丝束模型，该模型准确地捕捉了所制造的可变角度丝束层压板的特征。其次，采用三维详细有限元分析的冲击和冲击后压缩模型来预测变角度丝束层合板的失效行为，包括分层演化和裂纹扩展。从冲击和压缩后的冲击模型得到的结果进行了验证，对实验数据。
The development of variable angle tow technology has attracted growing attention in recent years due to its strong potential for structural tailoring. However, the full details of the failure mechanisms of variable angle tow laminates have been as yet unknown, and the design complexity also requires use of numerical analysis and novel techniques for variable angle tow composites. This paper addresses the two main problems for use of variable angle tow laminates in design. Firstly, a mathematical model is presented to build a three-dimensional variable angle tow model which exactly captures the features of as manufactured variable angle tow laminates. Secondly, impact and compression after impact models using three-dimensional detailed finite element analyses are presented to predict the failure behaviour of variable angle tow laminates including delamination evolution and crack propagation. Results obtained from the impact and compression after impact models are validated against experimental data.
