Description

technical field [0001] The invention relates to the field of glass fiber processing, in particular to a glass fiber reinforced composite material. 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 method, there is often a phase inte...

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
