fibre glass is also very light like carbon fibre and the reason it is used is to bring the cost down as if it was all made from carbon fibre the price would be expensive, this is the way most carbon fibre bonnets are made.

please tell me what laminating experience you have...................

Who's your carbon supplier, what resin are you using; seeing as there would potentially be cross contamination if you use a matrix specific resin
How many layers of glass/carbo will there be?

How are you curing them, air, autoclave or some other "method"?

Are you using a male or female mould?

Can you still use the original rubbers at the top of the window

Its a polyeurethane resin, used to lay-up both the fibreglass and carbon parts together - no problems with incompatability.

The layup weight will be about 800gsm - a compromise between rigidity and light weight.

Curing the panals is a combination of air, pressure from the mould and a curing catalyst - the same as normal fibreglass lamination

Although we'd love to use an autoclave, this would mean pre-preg carbon with an epoxy system, and the small matter of buying a pressure oven big enough to do the job... Pre-preg carbon costs £50 a square meter EACH LAYER, and thats before you factor in labour and the £500,000 autoclave

All the carbon is supplied from the industry leader 3M, and is laminated by experienced composite engineers.
