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?

Also be aware that most Polyurethane foams and model boards cause cure inhibition with many epoxy based pre-pregs when cured at elevated temperature.
