The present invention relates to the field of composite structures, overmolded composites structures and processes for their preparation, particularly it relates to the field of polyamide composite structures. The disclosed composite structures have a surface, which surface has at least a portion made of a surface polyamide resin composition, and comprise a fibrous material selected from non-woven structures, textiles, fibrous battings and combinations thereof, said fibrous material being impregnated with a matrix resin composition, wherein the surface polyamide resin composition is selected from polyamide compositions comprising a blend of a) one or more semi-aromatic polyamides (A) containing repeat units derived from aromatic dicarboxylic acids and aliphatic diamines, and b)one or more fully aliphatic polyamides (B) selected from the group consisting of polyamides containing repeat units derived from aliphatic dicarboxylic acids and aliphatic diamines, polyamides containing repeat units derived from aliphatic aminocarboxylic acids, and polyamides derived from lactams. |
