Zusammenfassung:	A hollow core composite assembly (10) is provided, including a hollow core base (12) having an open core surface (14), a solid film, for example a polyetherketoneketone film (22) applied to the hollow core base (12), and an adhesive layer (24) positioned between the solid film (22) and the open core surface (14). The resultant hollow core composite assembly (10) is cured to provide a structure suitable for use within a liquid molding process. A hollow core composite assembly (10) is provided, including a hollow core base (12) having at least one open core surface (14), a bondable solid film (22) applied to the open core surface (14), at least one dry face ply (30) laid up dry and placed on top of the solid film (22), and a liquid resin (32) applied to the at least one dry face ply (30) and then cured.
