Glass fiber is a kind of inorganic nonmetallic material with excellent performance, a variety of advantages are good insulation, heat resistance, corrosion resistance, high mechanical strength, but the disadvantage is brittle, wear resistance is poor. It is made of glass balls or waste glass as raw materials by high temperature melting, drawing, winding yarn, weaving and other processes, the diameter of its single wire is several microns to 20 meters microns, equivalent to 1/20-1/5 of a hair, each bundle of fiber is composed of hundreds or even thousands of single wire. Glass fiber is usually used as reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, electric subgrade board and other fields of the national economy.
Fiberglass fabric features introduced
Raw material and its application: glass fiber is higher than organic fiber in temperature resistance, non-combustible, anti-corrosion, heat insulation, sound insulation, high tensile strength, good electrical insulation.But brittle, poor wear resistance.Industrial filtration materials, anticorrosive, moistureproof, heat insulation, sound insulation, damping materials. It can also be used as a reinforcing material to make reinforced plastics (see color picture) or reinforced rubber. As a reinforcing material, glass fiber has the following characteristics, which make glass fiber more widely used than other kinds of fiber and far ahead of the development speed. The characteristics are listed below:
(1) high tensile strength and small elongation (3%).
(2) high elastic coefficient, good rigidity.
(3) the elastic limit has a large amount of elongation and high tensile strength, so it absorbs a large amount of impact energy.
(4) it is an inorganic fiber with good non-combustibility and chemical resistance.
(5) small water absorption.
(6) good scale stability and heat resistance.
(7) good processing ability, can be made into strands, bundles, felt, weaving and other different forms of products.
(8) transparent through light.
(9) the development of a surface treatment agent with good resin properties is completed.
(10) the price is cheap.
(11) not easy to burn, can be melted into glass beads at high temperature.
