Embodiment Construction

[0016] When reinforcing resin-based composite materials, tensile strength, tensile modulus of elasticity, flexural strength, and compressive strength are the main technical indicators to be considered. The above four indicators of the reinforced composite material with carbon fiber and glass fiber were also tested. The relevant conditions of the test are as follows:

[0017] Test method: According to the measurement methods in the national standard of the four technical indicators of tensile strength, tensile elastic modulus, flexural strength, and compressive strength.

[0018] Parameter setting: In the case of pure glass fiber reinforced resin composite material, the weight part of glass fiber is 55%, and the weight part of resin material is 45%. Enter the following table; the above-mentioned four indicators of the reinforced composite material with carbon fiber and glass fiber are also tested, wherein the weight part of glass fiber is 51%, the weight part of resin material ...

Abstract

A preparation method of a carbon fiber and fiberglass-combined reinforced composite relates to the field of a composite technology. The preparation method comprises the following steps: a, blending of base materials: weighing 1-15 wt% of carbon fiber, 45-70 wt% of fiberglass and 30-45 wt% of resin according to the weight ratio and uniformly mixing; b, preparation of a prepreg; c, spraying of a mold release agent for a mold; d, laying of the prepreg; and e, compression molding; and f, demolding. The prepared composite has light weight, high specific strength, high specific modulus, fatigue resistance, corrosion resistance, high temperature resistance and good dimensional stability, and has high cost performance. In addition, the method has few processes, is simple to operate, has high market promotion and application value, and can be used to significantly reduce weight of pure fiberglass reinforced composite parts and greatly enhance carrying capacity of aeronautics and astronautics devices.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a preparation method of a reinforced composite material using carbon fiber and glass fiber together. Background technique [0002] With the popularization and application of resin-based composite materials, more and more fields have begun to apply resin-based composite materials, while the use value of pure resin-based materials is limited, so it is necessary to add reinforcing fibers to resin-based materials to ensure resin-based composite materials. Composite materials have better strength. Therefore, in the prior art, two commonly used resin-based composite materials are glass fiber reinforced composite materials and carbon fiber reinforced composite materials. However, with the application of resin-based composite materials in the manufacture of structural parts, glass fiber reinforced composite materials can no longer meet the design strength requirements of str...
