Generally, composites, such as glass fibre and carbon fibre, are popular materials among manufacturers because of their light weight and mechanical properties compared to traditional materials, such as steel and aluminium. Composites can also be designed to take advantage of special coatings that help aid their integration into a product while improving functionality. Patrick Loock, segment business owner for products and applications at composite tubes and profiles manufacturer Exel Composites, discusses how composites manufactured with thermoplastic functional coatings can allow more control of properties such as friction, adhesion, and finish.
