Ecogel Cronos Project Succeeds in Reducing Curing Times of Composites
The Plastics Technology Center Aimplas, Valencia, Spain, participates in the European project Ecogel Cronos to develop an innovative and ecological high-productivity RTM process. For this purpose, the project has focused on the formulation and the manufacturing of new fast-curing powder gelcoats for composite parts.
At this point, the manufacturing times have been drastically reduced and the emissions from the workplace have been minimized. A final finish powder gelcoat has been obtained. It reduces up to 80 % the curing time compared to conventional liquid gelcoats. Likewise, it has been obtained a primer gelcoat with electrical conductivity in which curing time has been reduced compared to conventional ones. In this case, it is also relevant the fact that any other step in primer process is not needed.
Two study cases have been proposed in the project in order to demonstrate the advantages of the new technologies developed: a part of a tractor and a car door. After obtaining new powder gelcoats, project work is focused now on the development of composite molds in which carbon fiber laminate will assume a double function, acting at the same time as structural reinforcement in the mold and as a heat component that will provide a completely homogenous heat surface.
