Abstract

The invention discloses a carbon fiber cotton composite material and a preparation method thereof, and belongs to the technical field of materials. The carbon fiber cotton composite material comprises the following raw materials by weight: 9-15% of carbon fiber cotton, 70-80% of unsaturated polyester resin, 3-6% of mica powder, 4-7% of hollow glass beads, and 1-5% of a curing agent. According to the preparation method of the carbon fiber cotton composite material disclosed by the invention, the inner core and the outer layer of the composite material have different physical properties, and the inside and the outside of the composite material achieve required functional effects, the composite material finally has light weight and good flame retardance, high-temperature resistance, heat insulation, impact resistance and fracture resistance, and compared with a traditional glass fiber composite material, the weight of the carbon fiber cotton composite material is reduced by more than 30%.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a carbon fiber cotton composite material and a preparation method thereof. Background technique [0002] Fiberglass material, GFRP for short, also called GRP or FRP, is a kind of thermosetting plastic, and it is also an organic non-metallic material, including epoxy (EP), phenolic resin (PF), etc. 65%-70%. The reinforcement of GFRP is glass fiber, which acts as a reinforcement. It is an inorganic non-metallic artificial inorganic fiber, such as glass fiber, carbon fiber, etc., which accounts for roughly 30%-35% of the total weight. [0003] Fiberglass reinforced plastic (GFRP) has the advantages of light weight, high strength, and corrosion resistance, and has been widely used in construction, aviation, automobiles, and many other neighborhoods. [0004] With the development of science and technology, the society pays more and more attention to energy costs, and the demand fo...
