Problems solved by technology

[0004] At present, the thermoplastic composite material sheet is composed of fiber woven cloth impregnated with thermoplastic resin and then laminated. However, after fiber woven cloth is impregnated with thermoplastic resin, there will be delamination problems, resulting in poor bonding between layers.

Embodiment Construction

[0022] In order to have a further understanding of the purpose, technical effect and technical means of the present invention, the detailed description is as follows in conjunction with the accompanying drawings.

[0023] see figure 1 and figure 2 shown, where figure 1 Illustrated as a schematic diagram of fiber yarn bundles and resin strips in the fiber woven cloth of the present invention, figure 2 It is a schematic structural view of the fiber woven fabric of the present invention.

[0024] In this embodiment, the fiber woven cloth of the present invention includes several diameter yarns and several weft yarns, and the diameter yarns and weft yarns are alternately interwoven one above the other, so the warp and weft points appear alternately at a ratio of 1:1, and the fiber The woven cloth is a plain weave, wherein the diameter yarns and weft yarns are fiber yarn bundles 10 and resin strands 20 interlaced, that is, the fiber yarn bundles 10 and resin strands 20 are arr...

Abstract

The invention relates to the field of a fiber material, and particularly relates to a fiber woven fabric and a prepreg thereof. The fiber woven fabric disclosed by the invention comprises a pluralityof warp yarns and weft yarns; and the warp yarns and the weft yarns are alternately interwoven up and down, wherein both the warp yarns and the weft yarns are formed by interlacing fiber tows and resin thin strips. According to the fiber woven fabric and the prepreg thereof, which are disclosed by the invention, the fiber tows and the resin thin strips are subjected to hybrid weaving in the fiberwoven fabric, and resin impregnated in the prepreg is the same with the resin thin strip material, so that a resin impregnation rate is increased, and a specific gravity of the woven fabric is effectively reduced.

Description

【Technical field】 [0001] The invention relates to the field of fiber materials, in particular to a fiber woven cloth and its prepreg. 【Background technique】 [0002] With the development of electronic and electrical equipment and information equipment such as notebook computers, tablet computers, mobile phones, portable information terminals, and cameras, there is a strong demand for thin and lightweight products in the market. Thin and light products require thin-walled and light-weight shells and internal parts that make up the product, but also require high strength and high rigidity. [0003] Composite materials have the advantages of light weight, high specific strength and specific modulus, chemical corrosion resistance, fatigue resistance and easy integral molding, etc., and are widely used in the production of military, aircraft, wind power and other products; due to the excellent mechanical properties of composite materials, Therefore, it can also be applied to the...
