Ian how do you make your molds do you make a negative mold of the part then use that to lay the cf in ? and what do you use to make the molds ?

thanks for all the great info. I have a question about how you get such a nice finish on the side away from the mold? When I do it the peel ply leaves a rough woven finish and the perforated release film doesnt conform to curves very well.

We use a peel ply and it leaves a matt finish when removed and we can flow coat that with a clear resin to give a finish, but this is not a very good finish. We cut ALL our carbon fibre cloth to exact patterns to get it to conform to the shapes and the peal ply and breathers are cut to patterns too. If the cloth bridges across corners it will allow a void that will fill up with resin or hold air.

I use a smooth release film in my moldless laminations and I am able to obtain an almost smooth and uniform surface. It only leaves small bumps that are easily wet sanded off where the resin is sucked through the perforations. I have had real good luck in doing wet layup, and like Ian said, cut the cloth to a pattern and same with the film and bleeder. After laying the epoxy, I then let it cure for a few hours at around 70 dg F. then I place it in the bag and apply partial vacuum for about an hour and then apply full vac until cured. It comes out ready to trim and wet sand. If there are any unwanted dimples or anything I brush on a thin layer of epoxy and that is it. I make parts mostly for custom interior design so they need to be as pleasing to the eye as possible. I then proffessionally clearcoat them 4 times and buff and polish. Bam. That is it. Like I said Ian is the master and I hope to one day be doing bigger and better things. Thanx again for all the great stuff my man.

There is a lot of ways to use carbon fibre, the way I do my work will not suit a lot of other applications so it is interesting to see and hear how other people achieve their results. I have a friend that makes carbon boots for inline skates and they wrap the carbon over a male mould and then they use a shrink wrap as used in comercial food packaging and with a hot air gun they shrink the plastic and then once it cures they have a finish that is sanded and clear coated. I don't mind telling people how I do my work as it is mostly time involved and no short cuts to achieve a good result, putting the effort into doing all the processes I do properly. My process is not a very efficent method for mass production but I am mainly after a light, strong and durable componet and secondly cosmetically appealing part as most of my customers are motor racing teams.
