Hochleistungsverbundwerkstoffe mit einer hochreaktiven Epoxidharz/Haerter-Matrix und dreidimensionalen Fasergeruesten fuer Serienbauteile (S-RIM)

Series production of high-performance composite materials consisting of reinforced epoxy resin can be realized by structural reaction injection molding (S-RIM) using preformed fibre structures and injecting the epoxy resin/hardener mixture. The new epoxy resin/hardener system developed for the S-RIM process is characterized by high reactivity, low viscosity at process temperature (100 mPas at 95 C), good fibre wetting power, glass transition at >120 C and a hardening velocity of about 1 min per 1 mm wall thickness. Prototyping has been demonstrated with a frame carrier component for cargo trucks.
