Textile reinforcement forming quality with a complex shape depends strongly on the in-plane shear properties of the fabric. The tufting process is a relatively novel textile application to enhance the multi-layered reinforcement through-thickness. A new idea to influence the shear properties of a carbon woven fabric by incorporated tufts is investigated in the present paper. Based on the optical measurement, the in-plane shear characterisation through bias-extension test is employed to evaluate the effects of the in-plane tufting yarns directions, tufting density and width of tufting yarn on shear resistance. The experimental results clearly show that the appropriate choice of in-plane tufting yarns directions and the number of tufting yarns in one elementary unit in the woven structure can eliminate the defects during the shear deformation. Moreover, the mechanical models based on the bias-extension theory are proposed to interpret the shear deformation characteristics of tufted woven fabrics.

具有复杂形状的纺织品补强成型质量在很大程度上取决于织物的面内剪切性能。簇绒工艺是一种相对新颖的纺织品应用，可以增强多层增强织物的贯穿厚度。本文研究了一种通过结合簇绒来影响碳纤维织物的剪切性能的新思路。在光学测量的基础上，通过偏压延伸试验进行面内剪切表征，以评价面内簇绒纱线的方向，簇绒密度和簇绒纱线宽度对抗剪切力的影响。实验结果清楚地表明，在面内簇绒纱线的方向的适当的选择和簇绒纱线的在一个基本单元在编织结构的数目可以在剪切变形期间消除缺陷。
