I am working on a project to make a blade with fibre that has to be impregnated by resin under the action of vacuum. the resin has to be cured under vaccum pressure (no atmospheric air).
we had a try, and the resin is didn't cured well even after 24 hours.

Tell me is atmospheric air necessary for curing?
tell me how to reduce cure time for resin under vacum?

Maybe its too cold in the vacuum?
Infrared heater perhaps?

our project is related to mechanical engineering. not chemistry. We just want to cure somehow.

tell me some ways to reduce the viscosity of resin, the shopkeeper said, to mix the styrene. What do you say? will it work ? and what about the cure time when styrene will be added.
