FRP, Fiber Glass Reinforced Plastic, is a composite made from Fiberglass Reinforcement in Plastic (Polymer) matrix. A construction analogy would be the steel reinforcing bars in a concrete matrix for highways. By reinforcing the plastic matrix, a wide variety of physical strengths and properties can be designed into the FRP composite. Additionally, the type and configuration of the reinforcement can be selected, along with the type of plastic and additives within the matrix. These variations allow an incredible range of strength and physical properties to be obtained. FRP composites can be developed specifically for the performance required versus traditional materials: wood, metal, ceramics, etc.
Engineers can design the FRP composite to provide the needed characteristics, and avoid cost penalties of an over-engineered product.
