A plastic material strengthened by glass fibres, sometimes erroneously called
fibreglass. Glass-reinforced plastic is a favoured material for boat hulls and for the bodies and some structural components of high-performance cars and aircraft; it is also used in the manufacture of passenger cars.
Products are usually moulded, mats of glass fibre being sandwiched between layers of a polyester plastic, which sets hard when mixed with a curing agent.
