Introduction of fiberglass cloth:
Glass fiber is an inorganic nonmetallic material with excellent properties. Original name: glass fiber. It is glass ball or waste glass as raw materials by high temperature melting, drawing, yarn, weaving technology. And form all kinds of products, glass fiber monofilament diameter from a few microns to 20 meters microns, the equivalent of a human hair 1/20-1/5, each bundle fiber original SiDou have hundreds or even thousands of root of monofilament, usually as the reinforcing material in compound material, electrical insulation and heat insulation materials, substrate and so on, are widely used to national economy each domain.
Properties of glass fibre:
Glass is generally thought to be hard and fragile, not suitable for structural materials. However, when it is made into silk, its strength is greatly increased and it has softness. Therefore, it can finally become a good structural material when combined with resin to give the shape. The strength of glass fiber increases as its diameter decreases. As a reinforcing material, glass fiber has the following characteristics, which make the use of glass fiber far more extensive than other types of fiber, and the development speed is far ahead
Features are used as follows:
(1) high tensile strength and small elongation (3%). As for external wall
(2) high elastic coefficient and good rigidity.
(3) large elongation within the elastic limit and high tensile strength result in large absorption of impact energy.
(4) it is inorganic fiber with incombustible and good chemical resistance.
(5) low water absorption.
(6) good scale stability and heat resistance.
(7) good processing, can be made into strands, bundles, blankets, fabrics and other forms of products.
(8) transparency can pass through light.
(9) development of a surface treatment agent with good adhesion to resin.
(10) The price is cheap.
