Experimental and numerical studies of warpage in composite structures

该项目旨在通过实验和数值模拟相结合的方法来研究翘曲的基本原理。该项目的实验方面将包括复杂几何形状的翘曲测量，纤维和基质的材料表征，使用无损检测的纤维结构表征，并调查组成属性和中尺度结构如何影响翘曲。在数值模拟方面，将利用从实验研究中获得的成分特性和纤维结构数据，重点开发用于翘曲预测的有限元基础模型。该模型将根据实验翘曲测量数据进行验证，并用于研究使翘曲最小化的可能解决方案。

The project aims to study the fundamentals of warpage through a combined experimental and numerical simulation approach. The experimental aspect of the project will include warpage measurements in complicated geometry, material characterisation for the fibre and the matrix, fibre-architecture characterisation using NDT, and investigate how the constituent properties and the meso-scale architecture affect warpage. The numerical simulation aspect will focus on developing finite element bases model for warpage prediction, used the constituent properties and fibre architecture data obtained from the experimental study. The model will be validated against experimental warpage measurement data, and used to investigate possible solutions for minimising warpage.
