Why Epoxy Resin is a Top Choice in Composites Manufacturing
Epoxy resin plays a critical role in composites manufacturing because of its unique properties, especially when combined with carbon fiber. Epoxies are thermoset plastics, and as a resin, epoxy enhances the properties of carbon fiber by binding to the composite materials. Strength, durability, and resistance are all properties increased with the combination of epoxy resin and carbon fiber.
Because of these high-performance results, as well as epoxy’s ability to perform well in extremely high temperatures, the role of epoxy resin is especially significant in manufacturing carbon fiber composite products. The combination of carbon fiber and epoxy resin is adopted into many high-performance composites manufacturing applications that demand chemical resistance and mechanical strength in high-temperature environments.
The growth of epoxy in the composites industry
Epoxy resin in the global composites industry is expected to reach an estimated $4.4 billion by 2026 with a CAGR of 3.6% from 2021 to 2026. One of the major growth drivers of epoxy resins is the aerospace industry, which has adopted the use of composites and specifically epoxy resin in commercial aircraft applications and military aircraft.
Composites play a significant role in the manufacturing of Boeing 787 and Airbus 350 for primary and secondary structures, as well as aircraft interiors. Epoxy is often used in high-percentage composite airframes, such as the Boeing Company’s 787 Dreamliner and the Airbus A350 XWB.
The versatility of epoxy resin, when used with a wide variety of composite materials, makes it a viable choice for many composites manufacturing processes, including closed molding and filament winding, and various end applications. It is used in other markets including consumer goods, transportation, infrastructure, and wind energy. For the many applications that rely on carbon fiber and other reinforcements, the addition of epoxy resin offers strength that traditional resins do not.
