Research output: ThesisMaster's Thesis


For the production of alpine skis novel glass fibre laminates based on polyurethane matrix (PUR) are used, which offer a high potential for an optimization both in manufacturing process and mechanical properties. The objective of this master thesis was to investigate the effects of different press cycles by varying temperature, pressure and time on the static and fatigue properties of PUR based laminates in order to deduce possible processing-structure-property relationships. In total eight laminat qualities were produced by eight different pressing conditions, which consist of four plies bidirectional fiberglass fabric and a polyurethane resin, which is specially developed for wet lamination. Laminate structure and fracture behaviour of the laminates were characterised by using light microscopy. The mechanical behaviour of the laminates was investigated both in static and dynamic three-point bending tests. The fatigue performance was determined exemplarily on four out of eight laminates. The results of the static and dynamic tests showed a clear correlation between processing-structure and resulting mechanical properties. High flexural properties can be reached by a laminate structure which is compact and almost free of pores caused by a combination of high press temperature and high pressure conditions. The fatigue performance of the laminates showed a contrary picture to the static investigations. In the Wöhler-investigations the compact laminate structures show a good performance with high fatigue strength at low number of cycles (
