GEOMETRIC MODELING AND SIMULATION OF 3D WINDING LOOM FABRIC

Abstract

Abstract: According to the characteristics of the leno structure, a three-dimensional twist loom fabric is proposed. In order to meet the accuracy and authenticity of the three-dimensional twist loom fabric construction, the parameters of the fabric are characterized by the number of layers, the number of weft rows, the number of warp and weft threads, and the vertical weft distance organization. Then, according to the weaving process and fabric structure parameters, the warp yarn skeining law is studied to propose the law parameters of the warp system. Matlab is used to construct the warp curve to obtain the shape point. The shape point is used to obtain the control point. The cubic B-spline curve control point is used. The warp yarn system model is established, the structural parameter equations of the weft yarn system are proposed, the yarn section shape parameter equations are constructed, and the fabric geometric model is completed. Finally, Solidworks was used to construct a fabric simulation model to obtain a three-dimensional model of the fabric. The volume content of the unit cell fibers was calculated, which can be used for fabric performance analysis to achieve the designable purpose of composite material performance.
