Abstract

Composite articles comprising a porous prepreg or core layer and a powder coated layer thereon are described. In some instances, a thermoplastic composite article comprises a porous core layer comprising a web of reinforcing fibers held together by a thermoplastic material, and a powder coated layer disposed on the porous core layer, in which a particle size of the powder coated layer is selected to provide an interface between the powder coated layer and the porous core layer, wherein at least 50% by weight of the disposed powder coated layer is present above the interface.
