As the solubility of the plug is essential to the design, I am looking into lower temp prepregs. The complexity of the part makes infusion difficult in both the multi-layer layup as well as proper resin coverage under vacuum. ThanksI didn't really ask a question. Can anyone recommend a low temp prepreg? Or is anyone aware of a low temp that can be purchased in smaller quantities for prototyping?Thanks

+x Hanaldo - 12/7/2019 6:02:49 AMIs your intention to use the low-temp pre-preg to make a mould for high temp pre-preg use? If so, the Easy Composites XT135 has an initial cure temp of 65°, which would allow you to cure the mould and demould the plug, then do an elevated temp cure to use the mould at High temps
