Composites Curing

Curing in composites refers to the process where the composite materials, typically comprised of a resin matrix and reinforcing fibers, undergo a chemical reaction or heat treatment to solidify and form the final desired shape and properties. This stage is critical as it transforms the raw materials into a durable and structurally sound composite. Curing methods vary based on the type of matrix—whether it's a thermosetting resin like epoxy or a thermoplastic resin. Heat, pressure, or a combination of both are often applied during curing to activate the chemical reactions that cross-link the molecules within the matrix, creating a robust bond between the fibers and the matrix.
