Fiber Reinforced Polymer (FRP) composite materials are engineered materials made by combining a polymer matrix with reinforcing fibers such as fiberglass, carbon fiber, or aramid. The polymer matrix, often epoxy or polyester resin, binds the fibers together, creating a lightweight yet strong material with excellent mechanical properties. The manufacturing process typically involves layering the fibers in the desired orientation within a mold, saturating them with the resin, and then curing the composite under heat and pressure. FRP composites find extensive use in both the aviation and automobile industries due to their high strength-to-weight ratio, corrosion resistance, and design flexibility. In aviation, they are employed in aircraft structures, reducing weight and improving fuel efficiency. In the automobile industry, FRP composites are utilized for components such as body panels, chassis reinforcements, and interior parts, enhancing performance and fuel economy while providing durability and design freedom.

Answer:
Fiber-reinforced plastic (FRP) (also known as fiber-reinforced polymer) is a composite material made of a polymer matrix reinforced with fibers. Composites are established as an alternative material system to traditional materials such as steel, wood, aluminum and concrete. Bakelite was the first fiber-reinforced plastic.
Manufacturing of FRP:
- The manufacturing process of FRP composite materials requires a lot of heat and pressure to achieve the bonding of composite materials.
- Reinforcement: The process starts by pulling in two forms of fiberglass reinforcement. Creels of fiberglass roving provide unidirectional strength along the length of the profile, and rolls of woven fiberglass mat provide multidirectional reinforcement.
- Wet Out: The fiberglass reinforcements are pulled through a bath of thermoset resin — typically polyester or vinyl ester — as well as pigments to add colour, filler to enhance properties, and a catalyst to aid in curing.
- Surface Veil: Just before all the material is pulled into the heated die, a surface veil is added to enhance the surface appearance of the final product.
- Curing: Wet-out reinforcements are pulled through the heated pultrusion die, which begins the thermosetting process that causes the resin to “cure” or harden.
- Cutting: The finished product is then pulled to the cut-off saw and cut to the desired length.
Applications of FRP in aviation and automobile industry:
- Fiber-reinforced plastics are best suited for any design program that demands weight savings, precision engineering, finite tolerances, and the simplification of parts in both production and operation.
- A molded polymer artifact is cheaper, faster, and easier to manufacture than cast aluminum or steel artifact, and maintains similar and sometimes better tolerances and material strengths.
Hence, FRP material has a wide range of applications and uses in various industries. This material will bring input cost of any industries and improve quality of the products. This will bring benefits for the consumers as well as reduced input cost will reduce prices and reduce cost of the products as well.
