Problem with Out-of-Autoclave Tooling Prepreg System XT135

Group: Forum Members Posts: 16, Visits: 112	Hi, I made a mould with the Out-of-Autoclave Tooling Prepreg System XT135 following exactly the guide. But after demoulding my piece after the 1st cure (initial cure cycle) I discover that the surface of the mould has some imprefections. It look as there wasn't enough gel coat. Do you know where these imperfections are coming from? How can I remouve them? Thanks in advance

What is the pattern made from? Thanks for taking your time with my problem. I made it from the EB700 High Temperature Epoxy Tooling Board by the way I didn't yet make the post cure. Should I first handle the imperfection or hope that with the post cure cycle it would get better? Can I use the S120 Advanced Board & Mould Sealer to fill up the little holes?

Hi,, thanks a lot for your reply. I use only easy composites material. The finishing of the pattern surface is almost perfect. Do you confirm that you have to use only one layer of XPREG XT135/S? I....

The tooling board shouldn't be causing any problems at that temperature. The board sealer may well fill in the defects but it is not a permanent solution and may in time need re-application. What....
