Abstract

The invention discloses a 2.5 dimensional carbon fiber woven prefabricated part reinforced resin matrix friction material. The friction material is formed by combining and curing 2.5 dimensional carbon fiber woven prefabricated parts serving as reinforced structures and matrix resin glue. The specific preparation process comprises the steps of pretreatment of carbon fibers, preparation of the 2.5 dimensional carbon fiber woven prefabricated parts, preparation of the matrix resin glue and preparation of the friction material. According to the friction material, the carbon fibers are subjected to the pretreatment, and thus the carbon fibers are excellent in strength elongation property and weavability. Attachment warps penetrate through the material in the whole thickness direction, three-dimensional structures are formed, the delaminating problem is solved, the interlaminar shear strength is improved, the mechanical properties are outstanding, and the service life is prolonged; meanwhile, the preparation process is simple, and a product is low in porosity, uniform and compact, flat and clean in surface, low in production cost and easy to popularize.

Description

technical field

[0001] The invention relates to the fields of material science and processing technology, in particular to a friction material prepared by compounding and solidifying a 2.5-dimensional carbon fiber woven prefabricated body with a resin material. Background technique

[0002] Carbon fiber reinforced resin-based friction materials have a simple preparation process and have good thermal stability, mechanical properties and excellent friction and wear properties. They have been widely used in the automotive industry and have broad development prospects. In recent years, a large number of studies on carbon fiber resin-based friction materials formed by mixed fiber hot pressing have shown that the preparation process of fiber mixed hot pressing makes the friction material have the disadvantages of poor structural integrity, low designability, easy delamination and damage, and it is difficult to withstand large torsion. Torque, a defect that is prone to failure unde...
