摘要/Abstract

摘要： 仿形织造是利用不等长的经纬纱，在普通织机上织造具有一定曲面形状的织物。这些织物经过多层缠绕、树脂固化后就能形成一定立体结构的预制件，如椭圆形的压力容器、锥形管、圆环等。在仿形织物织造过程中，由于使用的是异型卷取轴，纬纱在卷取时要发生变形，形成剪切角。本文通过建立圆环形仿形织物的剪切变形模型，推导理论变形公式，将圆环形仿形织物的纬向剪切角计算出来，并将理论计算的剪切角与实测的剪切变形角进行对比，发现二者非常接近，证明该理论推导公式是正确的，符合织物剪切的实际情况。

Abstract: shaped weaving is a method which using unequal length of the warp and weft to weave shaped fabrics on the ordinary weaving frame. After multi-layer wound and resin solidified, these shaped fabrics can be formed into whole three-dimensional prefabricated parts, such as oval-shaped pressure vessels, conical tube, ring, etc. because the batch roller on shape weaving frame is cone frustum, not cylinder, which makes the shear deformation happens when tuck-in fabrics. In this paper, through the establishment of shear deformation model of the annular shaped woven fabric, and theoretical derivation on shear deformation, then calculate the weft deformation angle by theoretical formula. By contrast, we found the calculated shear deformation angle is very near to that measured on the shape fabrics. This proves the shear deformation model and theoretical derivation are correct, accord with the real situation of the shear deformation.

Key words: shape woven fabric, shear deformation, theoretical model, shear angle
