proper carbon fibre is a lot stronger hence being more expensive.
fibre glass is pretty light though.

I thought so too before but with this talk of cf and fibreglass it made me wonder

Depending on what you use, fibreglass can be stronger than carbon fibre. Carbon fibre has a higher strength to weight ratio than fibreglass however so you end up with lighter parts.
All depends on what you're trying to achieve.

Carbon fibre is more expensive than fibreglass as the process of producing carbon filaments is more expensive than producing glass filaments.

It also depends a lot on the resin and layup techniques too. If fibreglass was shit, they wouldn't make aeroplanes and boats out of the stuff.
My two pence at least.

for this purpose Fibreglass will be fine. However, I'm yet to see a GRP or FRP pattern part that is perfectly accurate though but that said many steel pattern parts aren't accurate either so you'll have to roll with panel gaps potentially.
The other issue with carbon is where the part has intricate bends/compund curvature/return lips/swage lines. You're stressing the material and can end up with distortion of the weave very easily. This leads to inherent weak/strong points.
I would guess that most pattern parts are spray laminated using a chopper gun to fire Chopped strands and resin at the mould surface, its cheap and effective but certainly not accurate as far as weight and thickness control go. I doubt they'll be made up of anything more than chop strand matt if they're hand laminated as the cost would be prohibitive to look at high end wovens

Actually, just looked at the links, they're seemingly well put together; the moulding work looks pretty good actually and I'd guess its been vac bagged or infused to get such a neat underside finish - but then making a tool suitable for infusion on a part which I wouldn't imagine would be used that often would be unusual.
Looks good though, both parts. There may be a bit of finishing/surface finishing to do before painting

I wouldn't have thought it would be much though, sanding any tooling seam lines and trimming the edges if they're not .
If Tom hasn't got one (which I would guess he has) The merka tools are awesome to use when working on any GRP/FRP and virtually zero dust, they use an abrasive mesh as opposed to a sanding pad and draw a vacuum through the centre. I saw a hand paint product go from terrible, unusable finish to glass finish in 20minutes last week, awesome tools

always go for carbon over fibreglass where possible, fibreglass is cheap because it doesn't last as long and is more prone to rusting, hence being cheaper
