Guestimating structural properties

I'm interested in finding out about calculating structural properties of laminates.  I know this will be a guesstimate as the direction of weave, resin type, vacuum achieved etc will have an effect but I was wondering if there's any guidelines. 

The reason I ask is because I made a wing a while back and used 1x200g, 3x600g layers.  It came out 2.34-2.38mm laminate thickness and was extremely rigid.  I could bounce up and down on it without fear of it breaking.  It weighed in at just under 4kg (with struts etc) so I'm keen to balance weight with strength.

Thought that might be the case, thanks Dave.
