For now I can't control the cool down ramp, but I'mm working to do it. Oven is 1,2m x 0,5m x0,5 m, 1Kw resistence, made with metal sheet and isolated outside, able to 120°C for now. Amber 8020 is very interesting. I have never try with prepreg at home, I usually do infusion (with the problem that a freestanding postcure need 10°C/h ramp...and I can't do it) sorry for my english Edited 13 Years Ago by _GABBER

Very very interesting I thought. http://www.gurit.com/sparpreg-featuring-airstream-technology.aspx Need confirmation from easycomposites team Leon I went to the site and all they said was how great it was without showing or explaining anything about it!
