Problems solved by technology

In order to solve this problem, a tough material is added to the brittle material, such as carbon and aramid fiber mixed interwoven fabrics, but the mixing ratio of materials with good toughness is inversely proportional to the tensile strength and modulus, and the tensile strength and modulus are inversely proportional. The tensile modulus has a large influence, and the extensibility is small

Embodiment 1

[0030] Multifunctional filament fabrics include non-woven fabrics and their prepregs, interwoven fabrics and their prepregs, warp-knitted fabrics and their prepregs using needle stitching; non-woven fabrics include 0°, -45°, 45° , the unidirectional yarn layer 5 of 90 ° direction, also can adopt the single item yarn layer 5 of any number of layers to be processed into cloth, and the unidirectional yarn layer 5 is closely arranged by any layer of several single filaments 6 or filament bundles, according to The ratio is placed into the spiral thread 1, and the spiral thread 1 is formed by a single filament 6 or a filament bundle, or a single wire or a single wire bundle, and spirals along the outer circumference of the core material 4 axially. Wrapping 2 into a winding layer, the winding layer is Z-direction or S-direction, and the core material 4 can also be wrapped around the first layer and then reversely wrap the second layer and more layers; so that the cloth can For long-d...

Embodiment 2

[0033] The outer layer of the spiral thread 1 winding layer, the spiral shape is formed by wrapping around a circle, and chopped strands 3 can be placed between the circles. One end of the chopped strands 3 extends into the winding layer, and the other end extends into the winding layer. Out of the winding layer, the protruding part is the same as that of another silk layer and extends into each other. After the subsequent processing of the composite material base material is cured, the interlayer fusion is strengthened. The core material 4 of the spiral thread 1 can be the same Homogeneous materials or non-homogeneous materials can also be used to mix different materials, and elastic rubber strips 7 can also be used.

Embodiment 3

[0035] The interwoven fabric can be arranged by placing either or both of the spiral thread strips 1 or the elastic rubber strips 7 in proportion in the warp and weft layers, and weaving into various filament interwoven fabrics or single warp filaments. Cloth, and then further processed into prepreg; needle seam warp knitted fabric can place one or both of the spiral thread strips 1 or elastic rubber strips 7 in any unidirectional thread layer 5 in proportion.

Abstract

The invention discloses a multifunctional long fiber fabric which comprises an interwoven fabric, a warp knitted fabric, a non-woven fabric and a prepreg of the non-woven fabric. The warp knitted fabric is manufactured by a multi-axial stitch-by-stitch method, any one or two of spiral slivers or elastic rubber strips are proportionally placed into any one single fiber layer, single sliver is wrapped and wound along the axial direction of a core material to form a winding layer of each spiral sliver, chopped fibers are placed between winding rings of the winding layer to form the single-layer or multilayer multi-axial long fiber fabric and the prepreg thereof, the multifunctional long fiber fabric has high elongation percentage and retraction performance of anti-collision functions, delaminating between layers is not easily caused, for example, the technology is applied to the non-woven fabric, the prepreg thereof and particularly a non-woven prepreg, fiber density ratio in unit volumeis increased, and various long fiber fabrics and prepregs of the long fiber fabrics in the technology are mainly used as reinforcing materials for manufacturing composite materials and can also be used as common fabrics.

Description

technical field [0001] The invention relates to a multifunctional filament cloth, especially a filament cloth with high tensile strength, anti-collision function and function of increasing interlayer shear force, and a prepreg cloth thereof. The filament cloth The main purpose is to strengthen the composite material, and it can also be used as ordinary cloth. Background technique [0002] Some filaments in the fabrics made of existing filaments are brittle, such as carbon fiber, glass fiber, etc. The composite materials made of such brittle filaments as reinforcing materials are easy to break when impacted. Equipment, the sudden fracture during impact will aggravate personal injury. In order to solve this problem, it is adopted to add tough materials to the brittle materials, such as carbon and aramid yarn mixed interwoven fabrics, but the mixing ratio of materials with good toughness is inversely proportional to the tensile strength and modulus, and the tensile strength an...
