复合材料三维编织工艺计算机辅助设计

The CAD of Three Dimensional(3D) Braid Technology for Composites

复合材料三维编织技术经过近几年的发展，得到了显著的提高。本文论述运用计算机进行三维四步法编织工艺辅助设计，主要包括编织挂纱核子运动分析、织物结构模型和工艺计算三部分，文章分别从设计原理、设计思想、程序流程三方面进行说明。经使用证明，所开发的CAD软件具有实用性、合理性和高可靠性等优点。

Three dimensional(3D) braid technology for composites has been developed for several years. The theory and software program structure of 3D braid technology CAD is discussed in this thesis. This CAD program includes 3D braided yarn carriers motion analysis, fabric geomtry structure model and calculation of parameters etc.. This CAD software has been applied in fabricating braided composites and has beed proved to be practical, suitable and highly reliable,
