[0024] Embodiments of the present application relate to a method for preparing a composite material comprising an anti-delamination wool fabric, comprising the following steps:

[0025] Step 1. Hook part of the fibers on the surface of the fabric with a crochet roller to form a wool fabric;

[0026] Step 2. Lay ordinary fabrics, single-sided wool fabrics or double-sided wool fabrics, apply pressure evenly, and combine the fabrics to form an anti-delamination laminated fabric, wherein the order of laying is that one ordinary surface is in contact with one wool surface Stacked;

[0027] Step 3, cutting the layered fabric described in step 2 as required, impregnating it with a polymer resin as a matrix in a mold, and then closing the mold and forming it by hot pressing to obtain the composite material comprising the delamination-resistant wool fabric;

[0028] Through the relative movement of the crochet roller on the surface of the fabric, the crochet hooks the transverse fiber...

Embodiment 1

[0039] A method for preparing a composite material comprising an anti-delamination wool fabric, comprising the following steps:

[0040] Step 1. Use the crochet roller to move relative to the surface of the glass fiber plain weave fabric, so that the crochet hooks the transverse fibers perpendicular to the direction of movement when the crochet needles are in contact with the fabric. Matte fiberglass fabric;

[0041] Step 2. Layer sequence design: Lay from the lower layer to the upper layer. The first layer is ordinary glass fiber plain weave fabric, which is the lower surface layer. The second layer is double-sided matte glass fiber fabric, which is the middle layer. The third layer It is an ordinary glass fiber twill fabric, which is the upper surface layer. There are three layers in total. A certain vertical pressure is evenly applied on the upper surface fabric to make the three layers of fabric tightly bonded, and each layer of fabric is laid according to the designed ang...

Embodiment 2

[0044] A method for preparing a composite material comprising an anti-delamination wool fabric, comprising the following steps:

[0045] Step 1. Use the crochet roller to move relative to the surface of the carbon fiber twill fabric, so that when the crochet needles are in contact with the fabric, they will hook the transverse fibers perpendicular to the direction of movement. Double-sided matte carbon fiber fabric;

[0046] Step 2. Layer sequence design: Lay from the lower layer to the upper layer. The first layer is ordinary carbon fiber twill fabric, which is the lower surface layer. The second layer is double-sided wool-faced carbon fiber fabric, which is the lower surface layer. The third to The fourth layer is a single-sided wool-faced carbon fiber twill fabric, with the wool side up, which is the middle layer, and the fifth layer is an ordinary carbon fiber twill fabric, which is the upper surface layer. There are five layers in total. A certain vertical pressure is eve...

Abstract

The invention provides a preparation method of an anti-delamination wool fabric composite material, comprising the following steps: (1) hooking part of the fibers on the surface of the fabric with a crochet roller to form a wool fabric; (2) using ordinary fabrics, single-face wool Layers of fabrics or double-sided wool fabrics are stacked, uniform pressure is applied, and the fabrics are combined to form an anti-delamination laminated fabric, wherein the order of laying is that one common surface and one wool surface are stacked in contact; (3) Step 2 The layered fabric is cut as required, impregnated in a mold with a polymer resin as a matrix, and then molded and hot-pressed to obtain the anti-delamination wool fabric composite material. The above-mentioned preparation method improves the interlayer peeling strength of the composite material, has better economic efficiency and product quality consistency, and is easy to standardize operations.

Description

technical field [0001] The invention relates to the field of resin-based composite materials, in particular to a composite material comprising an anti-delamination wool fabric and a preparation method thereof. Background technique [0002] The problem of easy delamination of multilayer composite materials is an important indicator affecting the comprehensive performance of materials. At present, there are some technical measures for delamination at home and abroad, such as fabric suture technology, three-dimensional weaving technology, Z-pin pin implantation technology, in-situ composite technology, X-core technology, yarn layering technology, quilting technology , Fiber needle felt technology, etc. [0003] These technologies have played a certain role in the project, but there are also the following problems: first, the production cost is high, second, the damage to the fiber is more serious during the production process, and third, there are more manual participation, an...
