HOT PLATE WELDING OF WOOD PLASTIC COMPOSITES BASED ON POLYVINYLCHLORIDE AND POLYPROPYLENE

摘要

In this work, fundamental investigations of the weldability of wood-plastic composites (WPCs) with high proportions of fillers were conducted at the Sueddeutsches Kunststoff-Zentrum (SKZ) using a hot plate welding process. The objectives of this research work were not only to obtain investigations about suitable welding parameters and possible process optimisations in relation to the welding apparatus and the weld strength, but also to determine the achievable weld quality regarding the lack of standards and guidelines worldwide on this field. A welding apparatus for the welding of WPC parts was designed and optimized for this purpose.
