Composite materials are products made up of two distinct physical states: one being a fibrous state and the other a continuous form distributed in a matrix. GFRP composite (or GF) is a fiber reinforced polymer made of plastic and reinforced with GFs in a continuous stranded fashion. The plastic may be a thermoset plastic (mostly epoxy, polyester, or vinyl ester) or a thermoplastic. The GFs are made from various categories of glass, depending on the end-use. GFs have silica or silicate along with some amount of oxides of calcium, magnesium, and sometimes boron. Fiberglass is lightweight and strong. It is not as strong as carbon fiber but is stronger than many metals. Additionally, its raw materials are comparatively cheaper than those of carbon fiber composites.
