Problems solved by technology

[0004] Existing double-layer fabrics cannot weave a higher thickness at one time, that is, the height of the pile in the interlayer is limited, generally no more than 30mm, and due to the lack of effective support points, when the pile height reaches more than 15mm, the composite material of the fabric There is a very significant decrease in the mechanical properties of
At the same time, when the existing double-layer fabric is bent and deformed, it will collapse at the place with a large curvature, that is, the upper and lower layers squeeze the pile yarn to make the local fabric thickness suddenly thin

Embodiment Construction

[0019] Referring to Fig. 1, the present invention constitutes double sandwich fabric by interweaving two warp yarn systems (ground warp and pile warp) with the weft yarn of the same system. According to the design of the fabric structure, the weft yarns of the same system are divided into upper layer weft yarns, middle layer weft yarns and lower layer weft yarns; 1. The upper layer weft yarn, the middle layer weft yarn and the lower layer weft yarn alternately introduced up and down are interwoven to form the upper layer fabric, the middle layer fabric and the lower layer fabric.

[0020] The upper layer is formed by interweaving the upper layer warp yarns 1, 2 and the upper layer weft yarn 11, the middle layer is formed by interweaving the middle layer warp yarns 3, 4 and the middle layer weft yarn 12, and the lower layer is formed by the lower layer warp yarns 5, 6 and the lower layer weft yarn 13 interwoven formations. The wefts 11, 12, and 13 in the upper, middle, and low...

Abstract

The three-dimensional hollow double sandwiched fabric consists of one upper layer interwoven with two upper ground warp layers and one upper weft yarn layer, and one lower layer interwoven with two lower ground warp layers and one lower weft yarn layer, as well as one middle layer interwoven with two middle ground warp layers and one middle weft yarn layer. The weft yarn layers in the upper layer, the middle layer and the lower layer are also interwoven with the poil warps, so that the upper layer, the middle layer and the lower layer are connected integrally to form one hollow double sandwiched structure. The fabric of the present invention is uses as reinforcing body of composite material, and the composite material with the fabric is light, high in impact strength, high in antiwear performance, high in bending performance and high in rigidity. The double sandwiched structure may be also used in heat insulation, anticorrosion, real-time monitoring, etc.

Description

technical field [0001] The invention relates to a three-dimensional woven hollow double-interlayer laminated fabric, which belongs to the technical field of composite material reinforced woven fabric structure. Background technique [0002] In civil textiles, there are piled fabrics made of natural fibers, such as warp velvet, plush and corduroy. Their common feature is the use of double-layered weave. According to the design of the fabric structure, the velvet is evenly sandwiched between the upper and lower layers of weave, and the lower woven fabric must be cut velvet. [0003] At home and abroad, there are already patents on the application of hollow laminated fabrics to composite material reinforcements. Domestic patents (00135845.6), (200610038306.1), European patents (DE19609492), (93119483.1) and US patents (5,175,034) introduce several types of laminated fabrics. Fabrics, but they are all single sandwich structures, and the main foreign manufacturer is PARABEAM BV ...
