A Novel Approach to Three-Dimensional Modeling of Interlaced Fabric Structures

摘要

This paper attempts the geometric modeling of woven and braided fabric structures in three dimensions using a computer aided geometric design (CAGD) technique. A new symbolic approach to fabric structure representation, which is useful to the textile CAD/CAM process and fabric design, is presented, and a basic model is proposed that treats a yarn as a three-dimensional solid object. Some traditional 2D fabric models are extended into 3D models and demonstrated in 3D form. The structures of various fabrics are demonstrated n graphic forms, including elementary weaves such as plain weave, twill, and satin; two layer fabrics; braided fabrics; and three-dimensional fabrics as reinforcements for composite materials.
