Hello everyone, I’m here to explain you my new idea of productive process and I need your help 
I’m going to use RFI (resin film infusion) but with some improvements for compression, I can’t afford (and I don’t want) an Autoclave, so I was thinking to compressed/clamped moulding system. This is my idea:
It all starts with a classic Fiberglass vinyl ester, hand made (I’m skilled) female mould, where the laminated stack is placed and vacuum bagged, maybe double bagged. Then it will start to heath…
When the resin is fully melted, a male mould, made of silicone and fiberglass (same as the female mould) will be pressed on the back of the vacuum bag. When the curing process starts the resin will decrease viscosity, the silicone will expand and help compressing the stack
I’m going to produce bike cosmetic parts, I don’t need any back surface quality
With a 5Ton press on a 30cm x 30cm mould I’ll get something like 5,5kg/square cm, so like an autoclave, at 120°C how much will the silicon expanding strenght be? Will my Vinylester mould collapse? I know that they are used in autoclave without problems…
Do you think that just clamping the two moulds with screws will be enough?
