FRP - Fiber Reinforced Polymers

By

Definition:

FRP (fiber reinforced polymer) is an acronym commonly used in the composite industry and it referees to plastic and polymer materials that are reinforced with structural fiber such as fiberglass, carbon fiber, or aramid fiber.

FRP can also be used as a replacement for the term "composite". Such as, "that boat is made out of FRP," instead of saying, "that boat is made out of composites."

Most often, FRP products are constructed using thermoset resins such as polyester, vinyl ester or epoxy, but they can also use thermoplastic resins such as polypropylene, PET, PEI, PEEK, PPS, and others.

The reinforcing fiber can not only be of various types (fiberglass, carbon fiber, or aramid) but the style of the fiber can very as well. The fiber can be discontinuous such as fiber that is found in chopped strand mat, or glass fiber used in gun roving. The fiber could be continuous direct-end roving, which is commonly used in filament winding and pultrusion.

Other constructions of fiber include woven roving and stitched fabrics. Woven is similar to other textiles, and structural fibers are interwoven. With stitched fabrics, layers of fiber are stitched together.

Fibers and fabric are then layered together to create a laminate. And the end result is a FRP composite product.

Also Known As: Composite, CFRP, Fiber Reinforced Polymer, Fiber Reinforced Plastic

My car is lightweight because many of the parts are made with FRP materials.
