Title:
【発明の名称】不均等機能複合材料のための強化用三次元織物及びその製造方法
Document Type and Number:
Japanese Patent JPH07122196
Kind Code:
B2
Abstract:
A three-dimensional fabric for reinforcing the composite material so that said material is irregularly functional with yarn orientation angle changed locally and optionally when weaving a three-dimensional fabric by the rotor-carrier type loom for such kind of fabric; and a method of manufacturing said fabric. In said fabric, a large number of yarns (1) oriented slantwise with respect to the lengthwise direction of the fabric are folded back at the surface of the fabric and interlaced with each other continuously in the lengthwise direction, and portions (32 to 35) at which inclination angles of continuous yarns (1) are partially varied between adjacent portions of the fabric are provided on a part of the section of the fabric. This fabric is woven in such steps that, during normal weaving cycle in which all rotors in the rotor-carrier type three-dimensional fabric weaving loom are divided into two groups each containing rotors not adjacent to each other so that rotors in one group are turned in one direction by 90 DEG or 180 DEG and then those in the other group are turned in the counter direction by 90 DEG or 180 DEG , a partial normal weaving cycle in which part of rotors are stopped from turning is repeated as many times as required.
