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  have been searching for Styrofoams which would be suitable for tube to tube process, but when I search I find many different types of Styrofoams and I don't know which one is suitable,
and the ones I find in the DIY stores are all used for insulation and as I understand they are not suitable for this process.

Could you please mention some exact names and material properties of the foam to search for?

regards,
Hadi
