Hi - I have searched for the answer to this - to no avail.  I would have thought it was an FAQ ...

Are there any rules of thumb to estimate the total weight of a carbon-fibre layup i.e. the weight of the carbon cloth plus the resin?

E.g:
1 layer of 200sgm CF including wet-lay epoxy = XX gsm
2 layers of 200sgm CF including wet-lay epoxy = YY gsm
3 layers of 200sgm CF including wet-lay epoxy = ZZ gsm

Is there a 'standard' ratio of CF to resin?

I only plan to make flat sheets, wet-lay, not infusion, but with pressure to squeeze out as much epoxy as possible.

I am planning to make some aero parts so weight is important.

Thanks!  CH

Brilliant - thanks folks.
