Problems solved by technology

[0005] All kinds of non-woven fabrics in the prior art are not suitable for application to the composite materials, and mainly have problems such as poor tensile strength, low fiber ratio in the volume of composite materials, and difficulty in injecting and soaking fluid substrates. For example, using fiber The network cloth method made by filament punching method, such as application number 201410035234.X, a continuous fiber nonwoven fabric and its manufacturing method, adopts single-layer or double-layer netting method, through needle punching, and slightly thermally bonded nonwovens

Embodiment Construction

[0029] The present invention is described in detail below in conjunction with embodiment:

[0030] Such as Figure 1 to Figure 4 Shown: the embodiment of the present invention is applicable to the composite material with fiber as reinforcement material and plastic as base material. The reinforcing material adopts carbon fiber, and the carbon fiber is a carbon fiber filament bundle. The tow 1 is arranged in a plane with multiple groups of tows, wherein the position of one or more than two groups of tows leaves a gap position 2 to form a unit group, and a plurality of unit groups are arranged circularly to form a single layer of flat surface . According to the single-layer mode, it is arranged into a single layer 3 in the warp direction, a single layer 4 in the weft direction, a single layer 5 on the left diagonally between the longitude and latitude directions, a single layer 6 on the right diagonally between the longitude and latitude directions, and a unit group of each lay...

Abstract

Disclosed is a non-woven fabric. The non-woven fabric is formed by bonding a plurality of layers. Each layer adopts a plurality of single set of densely-arranged tows, an empty gap position is arranged by a certain distance, short cut yarn is placed at the empty gap positions between the layers and the other parallel faces of a certain layer, warp direction and weft direction layers are adopted, left layers and right layers of diagonal lines between the weft and warp directions are adopted, and the non-woven fabric is formed by stacking and bonding the layers. According to the non-woven fabric, the tow specific gravity in the unit volume is increased, the diagonal directions between the weft and warp directions have the tensile strength, the shear force between the layers is increased, and the non-woven fabric is applicable to adopting fiber as reinforcing materials, plastics is the reinforcing material of the composite of the base material, the non-woven fabric is applicable to various purposes, and the non-woven fabric has the high tensile strength, high twisting power resistance, high interlayer shear force resistance and good softness.

Description

technical field [0001] The invention relates to the field of composite material manufacturing using fiber as a reinforcing material and plastic as a base material, including carbon fiber, glass fiber, aramid fiber, boron fiber and the like. Background technique [0002] The fiber part of the composite material used as a reinforcing material is currently mainly a woven fabric formed by interweaving warp and weft of fiber filament bundles, which is a composite material formed by thermosetting by hand lay-up, injection or pre-impregnation with liquid resin, but The buckling wave height of this kind of woven fabric due to the interweaving of warp and weft reduces the fiber ratio in the volume of the composite material, and the bending of the filaments reduces the tensile strength. [0003] The composite material product is generally formed by stacking multiple layers of woven fabrics, and the shear resistance between the layers is poor. [0004] The woven fabric interwoven with...
