多轴向叶片预制体三维织造成形工艺研究
Research on 3D Weaving Process of Multi-axial Blade Preforms
摘要
Abstract
In order to achieve the three-dimensional weaving of the multi-axial composite preform of composites,the microstructure of the multi-axial composite preform is studied,finding that there is a difference in the thickness of the single layer woven with orthogonal yarns and oblique yarns.A non-uniform thickness layering criterion for the three-dimensional model is proposed.A three-dimensional non-uniform thickness slicing testing program is developed based on Python,and the slicing test is conducted on the blade model to obtain the weaving range of each layer of yarns.According to the slicing results,the layers are woven layer by layer.The experimental results show that the three-dimensional model can be sliced into layers according to the non-uniform thickness slicing algorithm,and the woven profile of each layer can be used for the near-net shaping of the preform,which has important engineering significance for the near-net shaping of multi-axial irregular components.关键词
