Abstract
A hollow core composite assembly 10 is provided, including a hollow core base 12 having an open core surface 14, a polyetherketoneketone film 22 applied to the hollow core base 12, and an adhesive layer 24 positioned between the polyetherketoneketone film 22 and the open core surface 14. The resultant hollow core composite assembly 10 can be cured to provide a structure suitable for use within a liquid molding process.
