Here's the post about DIY preg I was telling you about from
www.racingcomposites.netAn alternative to resin infusion is impregnating the fabric before laying it in the mould. A sort of poor man's pre-preg! It actually has some advantages over pre-preg as you can use whichever resin you want without having to have a huge supply of pre-preg. Also it drapes very well without having to have an autoclave for a good finish. If the cosmetics of the part is important I'd recommend curing the first two layers to get a void free surface, then lay the rest in one hit.
First make templates of the part from which the part will be made;
Cut two pieces of 4mils plastic sheet (visquine) and lay one on your bench;
Next, pour some epoxy on the plastic and spread it to a thin film;
Lay the fabric on the resin an use a squeegee (bondo spreader) to squeeze the resin through.
Add more resin and squeegee it through until you can't squeese any more off. This will give you a good resin to fabric ratio.Too much will cause problems ,including poor surface finish, voids, porocity and weak parts.
Place another piece of visquine on top and smooth out the wrinkles with a rag.
You can now cut the fabric up using your templates or put it in the deep freeze
After cutting out the shape, remove one piece of visquine and lay in the mould (the fabric, not you!)
When its in place, remove the other piece of visquine.
Using a brush, tease the fabric into place.
Then bag it as usual.
