RESIN SPRAY TRANSMISSION (RST)
RST is a process whereby hot resin is sprayed directly onto a chilled mould that “freezes” the resin in place so that it cannot wet the laminate until the part is ready for cure. The next step is to place a dry fibre pre-pack onto the tool that is covered with the chilled resin. The Quickstep curing process commences by heating and melting the frozen resin thus wetting out the pre-pack as the resin melts on the mould face. Finally, the Quickstep curing process compacts, forms and cures the part in the mould.
This technology is expected to radically lower the costs for the material and labour components in a manufactured composite part.
Tool is sprayed with molten resin, which instantly “freezes” to tool face
Pre-manufactured dry pack is placed on tool. Vacuum bag is applied
Prepared tool is put into Quickstep pressure chambers and then cured
