Does anyone have experience with low temperature prepreg?

I am using a water-soluble plug material that gets a bit soft at 75c (the lowest I can test at the moment) thought the melting temp is somewhere around 200c. 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. 

Thanks

I 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

Is 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

The low-temp pre-preg would be used for constructing the part. Not making a mold. The plug is completely covered in carbon fiber. Sort of a 'Lost form' technique.
thanks I'll checkout that product
