A resin is a type of polymer that is used in the manufacture of composite materials. Composite materials are used in a variety of aerospace applications because they offer a combination of strength, stiffness, and lightweight properties that make them well-suited for use in aircraft and other aerospace structures.
Resins are typically used in conjunction with reinforcing fibers, such as carbon fiber or glass fiber, to create composite materials that have enhanced mechanical properties. The resin serves as a matrix that holds the fibers in place and provides additional strength and stiffness to the composite material.
There are many different types of resin that are used in the aerospace industry, including epoxy, polyester, and vinylester resins. These resins are chosen based on their specific properties and the requirements of the application for which they will be used.
