Low Temp Prepreg and Soluble Mold Material

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

Anyone know a supplier in the US that might sell pre-preg at smaller quantities? We're building working prototypes at the moment. 

APCM in CT, USA sells smaller quantities and they have a 180F system but I'm pretty sure it can be cured lower.  https://www.prepregs.com/
