What is FRP (fiber reinforced polymer)

FRP (fiber reinforced polymer) is commonly acronym in the composite industry, it refers to the structure of the fiber-reinforced, such as glass fibers, carbon fibers, or aramid fibers plastics and polymeric material.

Fiberglass can also be used as an alternative term "composite." Such as, "This boat is made of fiberglass," instead of saying, "This boat is made of composite material."

In most cases, construction of fiberglass products using thermosetting resins, such as polyester, vinyl ester or epoxy, but they can also be used thermoplastic resins such as polypropylene, PET, PEI, PEEK, PPS and so on.

Reinforcing fibers isn’t only a various types (glass fiber, carbon fiber, or aramid), but also there is a various of patterns of fiber. The fibers can be discontinuous, for example, in the chopped strand mat, or used in the gun roving. Fibers may be continuous straight end roving, which is commonly used in filament winding and pultrusion.

The other structural fibers include woven roving and stitching. Weaving like as other textile, and intertwined with structural fibers.  The sewing and fiber layers stitched together.

Fibers and fabrics, stacked together to form a laminate. Final production of glass fiber reinforced plastic composite products.
