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?

Thank you for the replies,

could you please give some more information about the tube to tube process?
is it like making all the parts seperately and connecting them togheter after curing?
but how about making a mould for tube to tube process? what material do you suggest for mould making?
( i don't have the equipment and machines to do negative moulding)

thanks
