METHOD AND APPARATUS FOR FORMING A COMPOSITE LAMINATE STACK USING A BREATHABLE POLYETHYLENE VACUUM FILM
20190232576 · 2019-08-01 ·

A method for forming a shaped composite structure. The method includes laying a composite laminate stack onto a mold, where the composite laminate stack comprises fabric laminate and resin and wherein the mold presents a predetermined shape, draping a vacuum film comprising polyethylene onto the composite laminate stack, thereby establishing an evacuatable volume between the vacuum film and the mold, applying suction to the evacuatable volume between the mold and the vacuum film to establish at least a partial vacuum within the evacuatable volume, thereby compressing the composite laminate stack via pressure applied to the vacuum film responsive to the at least partial vacuum within the evacuatable volume, and heating the composite laminate stack while applying suction to the evacuatable volume, thereby at least partially consolidating the laminate stack.
