The raw materials of chopped strand mat- fiberglass

FRP products typically used glass is a calcium - alumina borosilicate having alkali content of less than one percent. It is commonly referred to as "E" glass, as it was originally developed for the electrical insulation system.

The production of glass fiber by the molten glass from the melting furnace transport by platinum sleeve contains a lot of small holes, stretched into a glass filaments. Filaments for commercial use is usually between 9 and 15 microns in diameter. Before the filaments are gathered into fibers, are adhered emulsion. Fiber is very strong - tensile strength is particularly high. They also exhibit excellent chemical and moisture resistance, excellent electrical properties, from biological attack, and not burning, melting point of 1500 ℃ - in plastic reinforcing material performance is very good.

Fiberglass can use in a variety of ways, chopped into short lengths ("chopped strand"); gathered into a rope loosely bound ("roving"); woven into a variety of fabrics, yarn twisting and doubling obtained by continuous strands. In the UK, the glass fiber most widely used material is chopped strand mat, which material is made of glass fiber strands short cut into about 50mm, the use of polyvinyl acetate or polyester binder held together in mat form. The fiberglass chopped strand mat weight range from 100gsm to 1200gsm, and to have a common reinforcement used.
