Howdy,
In learning all this I have heard of the pre-preg CF. From what I can guess it does not unravel as easy?
I really do not have a clear understanding of the fabrics properties and how it really can make things easier.
I would love to get to the experience level of making a Carbon Fiber race seat, and with that I would want to use that wishbone lay on the first layer, down the middle of the seat.
Is this where I could benefit with pre preg?

p.s. someone please fix my thread header.... benefit..



If Brute Force Isn''''t working your not using enough...

I've got pin holing in my pressure bagged scope mould Paul - Any ideas what I can do about it ? I wonder if a breather /peel ply inside might help ?

Hi Steve,

Sorry for the delay in getting back to you about this point, I know we've developed a new method for you now which is working a treat so this is somewhat a mute point but to help others out there, it's oftena  good idea to combine a pressure bag with a vacuum bag. The vacuum will help to get any trapped air out of the laminate whilst the pressure bag puts the real pressure on. This would probably help with the pin holes quite a bit.

Best regards, Matt

I use your easypreg system and an aluminum mold, full vacuum with an active vacuum, and an oven but never able to get a pinhole free surface. Can you explain the difference between a pressure bag, and a vacuum bag? Any other tips would be appreciated.
