Autoclave molding is a process in which a composite preform—composed of single-layer prepregs laid up in a predetermined orientation—is placed inside an autoclave to undergo curing at a specified temperature and pressure. An autoclave is a specialized pressure vessel capable of withstanding and regulating specific temperature and pressure ranges. The composite blank is laid on a mold surface coated with a release agent, then sequentially covered with a porous non-stick fabric (film) and absorbent/breathable felt, sealed in a vacuum bag, and placed into the autoclave. Before heating and curing, the bag is evacuated to remove air and volatiles; then, heating, pressurization, and curing are carried out according to the curing profiles of the specific resins. This process ensures the shape and geometric dimensions of the parts. It is suitable for the molding of composite laminates and sandwich structures. This molding process is widely used for many large load-bearing structural components in the aviation and aerospace industries.
