Carbon Fibre Sheets

A mould really wouldn't be a hassle for this structure. As normal pacel tape is your friend (the brown parcel tape is mylar, and epozy just doesn't stick to it). Use some 3 by 1 or something like it strip wood, and make a construction like this. The underneath is the inside dimensions of your turret. The eupper piece is a bit larger all round, and will form the outside surface.
Glue a plate of ply to each side of the inner mould. Leave the outer one loose.



Start with a layer of peel ply, then laminate up your turret. I'd use two layers of cloth 45/45 (it with the fibres running diagonlly) then about 6 layers of unidirectional carbon, then another two layers of cloth. Then another layer of peel ply maybe two or three as you're new to this and will probably use too much resin. Now clamp your outer mould on top and leave to cure. When cured pll apart the mould and remove the peel ply.

Now to strengthen it some more it would be good to give it some ends. Make two flat plates of cloth, 4 layers, two diagonally, two vertically big emough to cover the ends. Compress between two bits of flat wood, with layers of peel ply between the parcel tape on the wood and the laminate.

When finished glue these onto the ends, use generous fillets on the inside and then run a couple of strips of 45/45 carbon down the joins. Finally cut a slot in the ends to clear your centreboard.

That was just the sort of process I'd planned, although thanks for the tip on laying up diagonally.

What is peel ply?  I had thought of using plastic sheet (damp proof course or similar) over the mould to prevent it bonding to the mould.

Peel ply is near enough to the stuff they line suits/dresses with... layed over the laminate and then ripped off when cured will give you a much better finish and help with squeezing excess resin out giving you a lighter end product.

Looks good!

How did you decide to do it in the end?

looks good. tres bon
