Abstract

The invention relates to a fiber composite material and a preparation method thereof, and belongs to the technical field of composite materials and preparation thereof. The problems that in the prior art, a fiber composite material is poor in heat conduction and corrosion resistance, and premature damage is caused by stress concentration are solved. According to the technical scheme, the composite material comprises the following raw materials: 30-40 parts of polyamide resin; 11 to 17 parts of jute fiber; 8-14 parts of a nylon toughening agent; 3-8 parts of black masterbatch; and 3-10 parts of a coupling agent. The jute fiber and the nylon flexibilizer are added into the polyamide plastic, so that the fiber composite material has the advantages of light weight and good thermal conductivity and corrosion resistance, the fiber composite material is higher in structural strength due to the addition of the jute fiber and the nylon flexibilizer, and the coupling agent is added to form a coating layer on the surface of the glass fiber, so that the service life of the fiber composite material is prolonged. The effects of a middle bonding layer and stress transmission are achieved; the preparation method is simple in process, convenient to operate, high in benefit, low in cost and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of composite materials and preparation thereof, and relates to a fiber composite material and a preparation method thereof. Background technique [0002] The traditional fiber composite material has poor thermal conductivity and corrosion resistance due to its simple composition. In addition, the stress of the traditional fiber composite material is relatively concentrated, which easily leads to the premature failure of the composite material. SUMMARY OF THE INVENTION [0003] In order to achieve the above object, the present invention provides a fiber composite material and a preparation method thereof, which solve the problems of thermal conductivity, poor corrosion resistance and premature failure caused by stress concentration in the fiber composite material in the prior art. [0004] The technical scheme adopted in the present invention is that a fiber composite material, in terms of weight, includes ...
