Glass fiber Reinforced Polyester (GRP) Works

Glass Fiber Rein Reinforced Polyester (GRP)


To produce a composite item has the style of any decorative finishing element, two basic components are required, these being a synthetic resin and a strong fiber. The resin, which could be a polyester, epoxy or vinyl ester, is normally supplied as a viscous liquid, which sets to a hard solid when suitably activated. The fiber may be glass, carbon, polyaramid, or a combination of some or all of these. What makes composites unique is the fact that the material of construction and the end product are produced simultaneously. Using a suitable mould, layers of fiber are impregnated with activated resin until the required thickness is achieved.
When complete, the moulding is removed and the mould can then be re-used to produce more 
identical items.

Polyester Resin
Polyester is often referred to as fiberglass – which is not technically accurate. Fiberglass is reinforcement and polyester is the resin.
Polyesters offer ease of handling, low cost, dimensional stability, as well as good mechanical,
chemical-resistance and electrical properties. Polyester resins are the least expensive of the resin
options, providing the most economical way to incorporate resin,
