Method of manufacturing a composite part comprising a core and at least one skin region

A method of manufacturing a composite part comprising a core (16) and at least one skin region (20, 22) formed of a skin polymer attached thereto, the skin polymer being a low-friction thermoplastic polymer, the method comprising the Mowing steps:

• a) providing a mold with a heatable mold cavity (4, 14);
• b) loading into the mold cavity a core element (6) having a surface with at least one contacting region provided with a plurality of anchoring sites (10, 28, 30, 34, 36), and—previously or subsequently—loading into the mold cavity a layer (2, 12) of the skin polymer in powder form adjacent said contacting region and embedding the anchoring sites;
• c) applying a heat pressing step whereby the skin polymer powder is molten to form a molten skin polymer matrix (20, 22, 32);
• d) applying a cooling step, whereby the skin polymer matrix solidifies to form a skin region mechanically engaged into the anchoring sites of the core element forming the core.
