How bad aceton is on Carbon composites?

I have a really hard time finding a D-Limolene supplier in Europe (D-Limolene is a solvent that dissolves HIPS plastic used as 3D printing material ) so my next best option is ABS . I want to print a mold core and after lamination to dissolve it , if i print in ABS i have to use acetone to dissolve it . I  must soak my core in acetone for an hour max , would this be enough to ruin my part ? I dipped a small part i made in acetone for couple of hours and i notice some small softening of the surface part but nothing major ,as far as i can see. Since i want my part to take loads i don't feel really comfortable using acetone . What is your view on this?

ABS will be better, but you will need a fair amount of acetone to melt out the print and even then you will probably still have bits stuck inside.

Im looking at using PC Polycarbonate filament next as its good for about 120degrees which opens it up to some of the more common prepregs, there are other options like HIPS material that you can use which is dissolved using limonene.

Or even BVOH could be a good option as its water soluble.

My first print was is HIPS but i cant find a limonene supplier that ships in Greece , Next PVA is semi flexible and very expensive 80 E/Kgr .I have never heard of BVOH its good to know about it but at 160E/Kgr is out of budget for me. I have never print PC sounds promising , i guess you plan to print a mold ... since for core use i don't know any way to dissolve it.
Anyway thanks for your insight.
