Problems solved by technology

[0002] Glass fiber is an inorganic non-metallic material made of silica. Its main components include silica, alumina, calcium oxide, etc. It is processed into finished products by melting, wire drawing, and weaving. Below a few microns; glass fiber has the characteristics of good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, and is widely used in industrial fields such as composite materials, insulating materials, thermal insulation materials, and circuit substrates, but glass fiber The characteristics of brittleness and poor wear resistance, and its excellent insulating properties make glass fibers unable to be used in the application field of conductive materials
