Problems solved by technology

[0002] As high-speed trains, wind blades, and yachts continue to improve the comprehensive performance of high-performance fibers and their products, higher requirements are placed on the interlayer connection and interfacial properties of materials. The interlayer connection strength of ordinary laminates can no longer meet practical applications.

Embodiment Construction

[0027] See attached figure 1 , the present invention is formed loop fabric by the warp yarn of three systems (ground warp yarn, binding yarn, loop yarn) and the weft yarn of one system interweaving. According to the fabric structure design, the weft yarns of the same system are divided into upper layer weft yarns and lower layer weft yarns; The weft yarns of the lower layer are interwoven to form the upper layer fabric and the lower layer fabric.

[0028] The upper layer 9 formed by the interweaving of the warp yarns 1 and 2 of the upper layer and the weft yarn 3 of the upper layer, the lower layer 10 formed by the interweaving of the warp yarns 4 and 5 of the lower layer and the weft yarn 6 of the upper layer, the weft yarns 3 and 6 on the upper and lower layers of the fabric are not included in this layer Outside the ground warp yarn 1,2 and 4,5 interweaving, also with binding yarn 7, loop yarn 8 is interwoven. This results in an integral fabric with loop yarns.

Abstract

The invention relates to a loop fabric, comprising an upper layer (9) formed by interweaving upper layer body warps (1) and (2) and an upper layer weft (3) and a lower layer (10) formed by interweaving lower layer body warps (4) and (5) and a weft (6); the number the upper layer and the lower layer is at least one. The loop fabric is characterized in that the wefts (3) and (6) on the upper layer and the lower layer of the fabric are respectively interweaved with a binder yarn (7) and a loop yarn (8) besides being interweaved with the body warps (1) and (2) and the body warps (4) and (5) on the same layers. The invention has the advantages of strong designability and suitability for scale weaving. Vast pile loops are attached to the surface of the invention, thereby effectively increasing the contact area among interfaces and reaching the aim of improving interlaminar shear property and delamination resistance of materials. Therefore, the loop fabric can be widely used as a wear-resistant material of bonding materials and composite materials among interfaces.

Description

technical field [0001] The invention relates to a looped fabric, which belongs to the technical field of special woven fabric structures. technical background [0002] As high-speed trains, wind blades, and yachts continue to improve the comprehensive performance of high-performance fibers and their products, higher requirements are placed on the interlayer connection and interfacial properties of materials. The interlayer connection strength of ordinary laminates can no longer meet practical applications. . Therefore, there is an urgent need for a material that can effectively improve the shear strength of the interface to more reliably realize the interface bonding between layers. The unique loop structure of the loop fabric can effectively increase the contact area between the interfaces. , can improve the interlayer performance by 20-80%. In addition, the fabric is integrally formed with a certain thickness, which can improve the compressive strength and shear strength ...
