Fiber reinforced plastic has greater flexural strength than timber and pound-for-pound is often stronger than steel and aluminum in the lengthwise direction.

Fibre-reinforced plastic (FRP) is a composite material made of a polymer matrix reinforced with The fibres are usually glass (in fibreglass), carbon (in carbon fiber reinforced polymer), aramid, or basalt. Reinforcement of the matrix occurs by definition when the FRP material exhibits increased strength or elasticity relative.

Fibreglass or glass fibre is a reinforced plastic material which is composed of a woven material that is embedded with glass fibres which are randomly laid across each other and held together with a binding substance. Fibreglass is combined with resin to form an extremely strong and durable composite.
