A Review on the Out-of-Autoclave Process for Composite Manufacturing

Composite materials have gained increased usage due to their unique characteristic of a high-stiffness-to-weight ratio. High-performing composite are produced in the autoclave by applying elevated pressure and temperature. However, process is characterized numerous disadvantages, such as long cycle time, massive investment, costly tooling, excessive energy consumption. As result, manufacturers seek cheap alternative reduce cost increase productivity. The out-of-autoclave (OoA) manufactures composites vacuum, pressure, heat outside autoclave. This review discusses common processes for various applications. theoretical practical merits demerits presented, areas future research discussed.
