Introduction Of Glass Fiber Reinforced Plastics

- Jul 25, 2017 -

Also known as FRP. A material made of glass fibres compounded with one or more thermosetting or thermoplastic resins. Because of its light weight, high strength, corrosion resistance and other advantages, so rapid development. The glass fiber in the raw material is fused with a glass ball and then drawn by a porous leaky plate. Commonly used resins are unsaturated polyester resins, epoxy resins and other thermoplastic resins (see polymer composites). The basic properties of this reinforced plastic depend on the fiber specifications used. Taking e-glass fiber reinforced epoxy resin as an example, its tensile strength is 150 kilograms force/mm, and the modulus is 4.2x10 acrylic/mm, density of 2.0 g/cm, specific strength of 7.5x10 mm, with a modulus of 2. $number mm. In order to improve the adhesion of glass fiber and resin, the silane coupling agent is used to treat the fiber, and the choice of silane type depends on the resin used.

This material is used in shipbuilding industry (28%), construction industry (about 20%), chemical corrosion-resistant container pipe (10%) and aircraft Industry (10%), and the rest for vehicles, machinery and consumer goods.
