Fiberglass is a common name of Polymer Matrix Composite materials reinforced by fine glass fibers.
The reinforcing dispersed phase may be in form of either continuous or discontinuous glass fibers.
Glass is widely used as a material for reinforcing fibers due to the following its properties:
The types of glass used for fiberglasses are as follows:
Glass fibers are manufactured from molten glass, from which glass monofilaments are drawn and then gathered to strands. The strands are used for preparation of different glass fiber products (yarns, rovings, woven fabrics, mats).
The most popular matrix materials for manufacturing fiberglasses are Thermosets such as unsaturated polyesters (UP), epoxies (EP) and Thermoplastics such as nylon (polyamide), polycarbonate (PC), polystyrene (PS), polyvinylchloride (PVC).
Fiberflass materials usually have laminate structure with different fibers orientations in the reinforcing glass layers. Various glass fibers orientations result in anisotropy of the material properties in the plane parallel to the laminates. Concentration of glass fibers in fiberglass is normally about 40% - 70%.
Fiberglasses (Glass fibers reinforced polymer matrix composites) are characterized by the following properties:
Fiberglass materials are used for manufacturing: boat hulls and marine structures, automobile and truck body panels, pressure vessels, aircraft wings and fuselage sections, housings for radar systems, swimming pools, welding helmets, roofs, pipes.
