Problems solved by technology

[0003] a) The material is plastic, paper or aluminum alloy as the core material, such as patent 00101336.X, 99239053.2, 92243853.6, US6267838B1, special open 2002-67195, the production is by bonding, riveting or welding, and the process It is more complex, and paper and plastic honeycomb core materials are not suitable for occasions with high temperature requirements;
[0004] b) Although the patent 00135845.6 relates to the hollow structure of high-performance fibers, it is a woven fabric and is limited to weaving together with the upper and lower fabrics
[0005] c) Although the hollow honeycomb structure is involved in the patent 97112582.1, the expansion of the honeycomb structure must be completed by inserting the expansion body, and it is a woven fabric, which is complicated to process and use

Embodiment Construction

[0011] exist figure 1 In the rib arrangement of the knitting needles on the double needle bed, all the knitting needles knit in a circle in each way. Weaving with glass fiber 1. The knitting method is best to use the opposite eating method, so that under a certain bending depth and bending angle, the number of needles participating in the bending is as small as possible at the same time, the purpose is to reduce the damage to the yarn, especially when weaving glass fiber When other high stiffness fibers. Based on the same purpose, when the fabric density is constant, the weft knitting machine with the lowest possible gauge is used for weaving.

[0012] Due to the use of glass fibers with a monofilament diameter of 13 microns, the rigidity of the fibers is relatively high, so that the appearance of the standard rib structure is deformed towards a higher support trend after the coil structure is unmachined.

Abstract

A method for weaving the gap structure of ligh-weight composite material by dual-surface weft knitting machine with two needle beds features that the high-performance high-rigidity fibres or yarn is used as raw material for dual-surface knitting. Its advantages are light weight, complex shape and high-temp environment.

Description

technical field [0001] The invention relates to a method for manufacturing a lightweight composite void structure reinforcement, in particular to a double-sided knitting weaving on a double-sided weft knitting machine with high-performance or high-rigidity fibers or yarns as raw materials, and the weaving becomes Methods for use as void structures and core materials for lightweight composite reinforcements. Background technique [0002] At present, the known lightweight composite materials, especially the core layer used as the composite material, generally have three types of structures, one is a foamed plastic microporous core material, the other is a honeycomb core material, and the other is a corrugated core material. The latter two are used for composite structural parts with strict mechanical performance requirements and light weight requirements. But there is one of the following characteristics: [0003] a) The material is plastic, paper or aluminum alloy as the co...
