Hello,
I want to make a bicycle frame by prepreg vacuum bagging process . I am going to use foam as a mold.
I am looking for a foam to withstand the temperature that the prepreg needs to cure.
what type of foam do you suggest?

Hi,
I actually changed my mind since making this parts with prepreg is gonna cost me a lot . i want to switch to hand layup process.
is it possible to use Styrofoam as a mold in this case? i mean to shape the Styrofoam, and place the carbon layers and then peel ply . i want to use a resin which would be cured in room temperature. do you think Styrofoam is suitable for this process? if not what kind of foam do you recommend ?
if yes, my next question would be about how to make the Styrofoam stiff enough before placing the layers? is there any kind of wax to do this? just to prevent the Styrofoam from being damaged.

thank you for the helps
