Problems solved by technology

However, styrene in unsaturated resin is a pungent odor, toxic substance, and volatile, so it will pollute the environment
Moreover, the heat resistance and mechanical properties of unsaturated resin are poor, which also limits its application in higher demanding fields.

Abstract

The invention discloses a glass fiber modified epoxy resin composite material, which is prepared from the following components in parts by mass: 60 to 80 parts of epoxy resin, 10 to 30 parts of filler, 5 to 15 parts of epoxy resin reactive diluent, 20 to 40 parts of curing agent and 20 to 30 parts of glass fiber. The composite material provided by the invention overcomes the heavy smell of styrene volatilized in the production process through the composite material using epoxy resin instead of unsaturated resin, the styrene is a toxic substance with an irritating smell, has volatility, and can pollute the environment, so the governance cost is high; mechanical properties and heat resistance of the epoxy resin is better than that of the unsaturated resin; the preparation process is simple, the processing is easy, and the processing cycle is short.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material of glass fiber modified epoxy resin and a preparation method thereof. Background technique [0002] Glass fiber reinforced polymer composite materials have relatively high strength and rigidity. FRP products have the characteristics of light weight, high strength, corrosion resistance, good electrical properties, good thermal properties, and good designability. They are resistant to air, water, and general concentrations of acids, Alkali, salt, and various oils and solvents have good resistance. At present, FRP has been widely used in military industry, aerospace, automobile industry, building materials, sports and leisure equipment and other fields. Glass fiber reinforced resin-based composite materials are a series of high-performance composite materials prepared by using advanced composite molding and processing methods with resin as the matrix...
