Abstract
An improved method and apparatus for preventing buckling of thermoplastic composite laminates during an autoclaving process. Edge strips are placed around the periphery of the laminate to prevent the vacuum bag of the autoclave from making contact with the edges of the laminate when the autoclave is pressurized. As a result, the vacuum bag is prevented from imparting inwardly directed forces to the edges of the laminate which could otherwise cause the laminate to buckle.
