Prepregs, cores and composite articles are described that comprise lighter weight materials and/or lower amounts of adhesive than commonly used. In some instances, one or more components of the articles may comprise a repellent material or repellent treatment to reduce the overall absorption rate of adhesive into the components of the article.

Prepregs, cores, composites and articles including repellent materials

A thermoplastic composite article comprising a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material is provided. In certain instances, the article further comprises a skin layer disposed on the core layer and an adhesive layer between the core layer and the skin layer. In some configurations, the adhesive layer comprises a thermoplastic polymer and an effective amount of a thermosetting material to provide a post-molding peel strength between the skin layer and the post lofted core layer of at least 0.5 N/cm (in either or both of the machine direction or cross direction) as tested by DIN 53357 A dated Oct. 1, 1982.
