Problems solved by technology

Since the composite material is made by mixing two or more materials together through an auxiliary method, there is often a phase interface between the materials due to different properties, which will eventually cause changes in the shear force between the interface layers. Composite materials perform poorly
[0003] With the continuous development of the economy, the demand for glass fiber in industrial smelting, welding and other industries has surged. At present, some alkali-free glass fibers are used, which have a very short life and poor heat insulation. damage, thus endangering personal safety, its acid and alkali resistance, rigidity, anti-aging and high temperature resistance performance need to be improved

Abstract

The invention provides a preparation method of a glass fiber composite material. The preparation method comprises the following steps that a, glass powder, selected high filter residue, calcium oxide,magnesium oxide, titanium dioxide, aluminum oxide and silicon dioxide are mixed and smashed, and mixed powder is obtained; b, a substrate material, glycidyl methacrylate, sodium pyrophosphate and pentaerythritol ester are mixed to be uniform and melted to be at a molten state, and a first material is obtained after heat preservation is conducted; c, the mixed powder is added into the first material and melted and stirred, then subjected to fusion wiredrawing, and a crude product is obtained; and d, the crude product is subjected to acidification treatment, treatment is conducted on the crudeproduct by using a silane coupling agent, heat treatment is conducted consecutively, and finally drying is conducted. The prepared glass fiber composite material has good ablation performance, betterhigh temperature resistance, the chemical corrosion resistant property and the elasticity modulus.

Description

technical field [0001] The invention belongs to the technical field of glass fiber materials, and in particular relates to a preparation method of glass fiber composite materials. Background technique [0002] Glass fiber has excellent properties such as good insulation, low thermal conductivity, and strong sound absorption. In recent years, it has been widely used in aerospace, military chemical and other fields. Among many polymer composite materials, fiber-reinforced composite materials have attracted widespread attention because of their excellent comprehensive properties, such as high impact resistance, high modulus, high mechanical properties, and high wear resistance. Glass fiber has the advantages of good corrosion resistance, heat resistance, good mechanical strength, and low raw material prices, and is widely used in composite materials for reinforcement purposes. Since the composite material is made by mixing two or more materials together through an auxiliary me...
