Fiberglass coating is a kind of inorganic non-metallic material with excellent properties, which has many advantages, such as good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is brittle, poor wear resistance. It is a glass ball or waste glass as raw materials by high temperature melting, drawing, winding, weaving and other processes, its monofilament diameter of several microns to more than 20 meters’ microns, equivalent to a hair silk 1/20-1/5, each beam of fiber raw wire by hundreds of or even thousands of monofilament composition. Fiberglass coatings are often used as reinforcement materials in composites, electrical insulation materials and insulation materials, circuit substrates and other areas of the national economy.
Glass, the concept of the general person is hard and fragile objects, not suitable as a structural material, but if it is added to the wire, its strength is greatly increased and has a softness, so with the resin given shape can finally become a good structural material. The strength of fiberglass increases with its smaller diameter.
