Fibreglass (US: fiberglass) is a composite material. It is a fibre-reinforced polymer made of a plastic reinforced by fine fibres made of glass. The composite material may be called glass-reinforced plastic (GRP).
Fibreglass is cheaper and more flexible than carbon fibre. It is stronger than many metals (when compared by weight), and can be moulded into complex shapes. The plastic matrix is usually a thermoset polymer – such as epoxy or polyester resin, or it may be a thermoplastic.
The benefits of fibreglass include:
- Has a good weight to strength ratio
- Is corrosion resistant
- Is water resistant
- May be light-weight
- Is non-conductive

- Sail planes, Sports cars, micro cars, karts, lorries, wind turbine blades.
- Pods, domes and architectural features where a light weight is needed
- Roofing products, swimming pools and composite housing
- Protective sleeving for RF Antennas

- Piping for above and below ground systems
Use of the term[change | change source]
"Fiberglass" refers to the complete glass fiber reinforced composite material, rather than just the glass fibre inside it.
