Hi all!

I am intending to create an organic form sofa in CF. It's somewhat similar to the picture I've included below but a much smaller 2-seater version. My limitations are that I do not have space for a curing oven. Here are my concerns:

1) If I cannot cure an item in an oven, it means I will have to use room temperature cure resins and the means a hand layup method?

2) What can I make the mould out of? Is it a frame of wood with PU foam block for the the shape? If I do, how do I vacuum bag such a large mould?

3) Since the mould is likely to be a 'pool'-shaped form, can place a sheet over it and fill it up with water as a replacement over vacuum bagging? Would the high specific heat capacity of water affect the curing of the resin as it pulls heat away?


.

Cheers and thanks in advance,
Kai
