Fibre reinforced polymer composites to strengthen structures

The state of the industry typically, the term fiber reinforced polymer (frp) composite is used to describe product applications in the aerospace, military or recreational industries, (eg skis, boats, race cars, or golf clubs. Fibre-reinforced plastic (frp) (also called fiber-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibres the fibres are usually glass (in fibreglass ), carbon (in carbon-fiber-reinforced polymer ), aramid , or basalt. Fiber-reinforced polymer (frp) composites are formed by embedding continuous fibers in a polymeric resin matrix which binds the fibers together common fibers used in frp composites include carbon, glass, aramid and basalt fibers while common resins are epoxy, polyester, and vinyl ester resins. Well-designed and manufactured glass fiber reinforced polymer composite structures have several advantages over steel and conventional concrete structures such as high strength-to-weight ratio, good stiffness, good corrosion resistance and good damping capacity.
