glass/ carbon to epoxy/ resin ratios?

There's a good section in the second Bethwaite book about this. As I understand it, epoxy is actually more elastic than polyester resin (ie it stretches more before breaking), which is why it is a good resin.  The resin is really only there to bond the fibres together, so you want as little resin as you can get away with.
