Hello, I am going to make some Uni-mould moulds from original parts that are too light and delicate to see any heat or pressure. Then, I am going to make pre-preg parts from the moulds.
I just wondered what peoples experiences of this were... What temperatures have you used the moulds to? What pre-preg have you used in the moulds? Etc...
In another thread, Hanaldo suggested an extended post cure which I intend to do. Someone else mentioned board sealer which could be a good shout as I have spray facilities for this. I also have access to an autoclave for when I make the final part. Obviously, the integrity of the mould will come down to how well it is laminated but I was hoping to use a prepreg that might be a little more suited to OOA/lower temp cure. I have looked for VTF261 but may end up with VTC212 or similar. Any pointers on this will be much appreciated as I have a few projects coming up that would be suited to this process (if it works!) Many thanks in advance!
