%X The goal of EU-funded project "LOWFLIP" (= low cost flexible integrated composite process) is the development of low cost manufacturing processes for composite parts using automated handling solutions, multifunctional low cost toolings and tailored fast-curing prepreg materials. These so called "snap-cure" prepregs are based on heavy-tow (50k) carbon fibers and a novel epoxy resin system developed by SGL that combines fast curing at elevated temperatures (e.g. 15 min at 120°C) with a long shelf-life at room temperature (4 weeks). The glass transition temperature of 125°C and its rapid buildup allow for a quick demoulding of manufactured composite parts. Tailored tack for automated processes such as pick & place or tape laying applications and the possibility to use out-of-autoclave curing methods are additional key features of the developed materials. The development of these new snap-cure prepreg materials and their properties are subject of this paper.
