Abstract

The invention discloses a carbon fiber/epoxy resin composite material comprising solid epoxy resin, a curing agent, an organic phosphorus fire retardant and carbon fiber, wherein the solid epoxy resin is formed after liquid epoxy resin is crosslinked and cured, and the curing agent is used for crosslinking and curing the liquid epoxy resin. The carbon fiber/epoxy resin composite material takes the organic phosphorus fire retardant as the fire retardant, and a decomposition product of the fire retardant and a combustion product of fire retardant epoxy resin contain fewer corrosive substances and toxic substances, so that secondary pollution to the environment is greatly reduced. The organic phosphorus fire retardant is strong in solubility and easier to disperse in epoxy resin. The organic phosphorus fire retardant as the fire retardant in the carbon fiber/epoxy resin composite material is low in usage and good in fire retardant effect. The carbon fiber/epoxy resin composite material is simple in preparation method and easy for large-scale production.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a carbon fiber / epoxy resin composite material and a preparation method thereof. Background technique [0002] Fiber-reinforced composites have many excellent properties, such as high specific strength and specific modulus, designable performance, and easy overall molding, making them widely used in military and civilian fields, especially in the field of aerospace. At present, the application of fiber-reinforced composites in the automotive field has also attracted great attention, especially carbon fiber / epoxy composites. Carbon fiber / epoxy resin composite material is a high-strength composite material, mainly composed of carbon fiber as a reinforcing material and epoxy resin as a matrix material. It has high specific strength and specific modulus among many lightweight materials. The effect is very obvious. [0003] With the improvement of people's awareness of fire safety,...
