Matrix Model of 3D Textile Composites Reinforcement Structure

为了提高三维纺织复合材料增强体结构的设计效率,以贯穿正交机织物为例,在分析交织规律的基础上,提出了反映交织规律的矩阵模型,并给出了矩阵生成的算法。矩阵模型的列向量、行向量分别代表经、纬纱,其中以元素"1"、"0"分别表示接结经纱交织规律的经、纬组织点,以元素"3"、"2"分别表示地经纱交织规律的经、纬组织点,并建立了贯穿正交组织矩阵列向量之间元素的对应关系及矩阵生成算法。研究表明,提出的矩阵模型及其生成算法,能快速、准确设计出贯穿正交机织物组织矩阵,从而提高该类三维纺织复合材料增强体结构的设计效率。

In order to improve the design efficiency of the three-dimensional textile composite reinforcement structure,taking the through-thickness orthogonal woven fabric as an example,a matrix model was proposed on the basis of analyzing the interlacing rule,and the generation algorithm of matrix was given too.The column vectors and row vectors of the matrix model represent the warp and weft respectively,and then the warp float points and the weft float points of bind-warp were respectively represented with"1"and"0",while the warp float points and weft float points of ground-warp were respectively represented with"3"and"2"in matrix model.The corresponding relation of elements between column vectors of matrix and the algorithm of matrix generation were established.The results show that the proposed matrix model and its generating algorithm can quickly and accurately design the matrix of through-thickness orthogonal woven fabric and improve the design efficiency of this kind of3D woven fabric.
