Abstract

The invention provides a resin-based carbon fiber composite material reinforced laminate and a preparation method thereof, belonging to the field of lightweight composite material forming. The preparation method of the reinforced laminate comprises: selecting a steel foil with a thickness of 0.01-0.04 mm, sequentially washing the steel foil at a constant temperature with a sodium hydroxide solution, a mixed solution of hydrogen peroxide and ammonia water, and then placing it in a silane modification solution for immersion ; The resin-based carbon fiber composite material and the modified steel foil are alternately layered to form a laminate, and then the laminate is placed in a hot pressing device for heating and curing. In this method, the surface-modified steel foil is added between the layers of the resin-based carbon fiber composite material, so that the steel foil can be embedded in the interior of the resin between adjacent carbon fiber composite materials to form a strong interaction force, thereby increasing the resin matrix. The effect strength of the carbon fiber composite material perpendicular to the fiber direction, and improve the connection performance between adjacent layers of the resin-based carbon fiber composite material.

Description

technical field [0001] The invention relates to the field of lightweight composite material forming, in particular to a resin-based carbon fiber composite material reinforced laminate and a preparation method thereof. Background technique [0002] Resin-based carbon fiber composite material is a composite material with resin as the matrix and carbon fiber as the reinforcing phase. The material has the characteristics of high temperature resistance, radiation resistance, high strength and chemical corrosion resistance, and is currently widely used in aerospace, shipbuilding, transportation and military industries. Carbon fiber composites have higher modulus and strength, but this is the property provided by the fiber, and the direction perpendicular to the fiber is provided by the matrix resin. Compared with the excellent properties of the fiber, the performance of the resin is a major factor of the material shortcoming. Although this situation can be improved by laying lay...
