三维立体织物复合材料研究与进展

Research and progress of 3D stereo fabric composite

三维立体织物复合材料是近年来发展较为迅速的一种新型材料,作为增强体的三维立体织物具有优异的结构可设计性,克服了传统二维织物层间剪切性差的缺陷,同时也解决了层合板易分层的问题。介绍了三维机织复合材料、三维针织复合材料和三维编织复合材料的结构及其特点。

3D composites are a new type of materials developed rapidly in recent years.The 3D stereo fabric as an enhancement has excellent structural design ability,which overcomes the defect of poor interlaminar shear between the traditional 2D fabric.At the same time,it also solves the problem of easy stratification of laminates,so it attracts many scholars.It was mainly described that three aspects:3D woven structure,3D knitted structure and 3D braid.
