Composite doubt.........

perfectz

Composites are so cool and they make me go wild......
I have the composite paper only in my 6th semester and I am only in 3rd semester.....
I was wondering if there are any online calculators to check out the properties of composites. I wanna work out with various combinations of reinforcements and matrices and check out the results.......
Somebody please help me.
How can I calculate the various engineering properties like strength(tensile, compressive), stiffness, modulus of elasticity and rigidity of composites?
I know there are sources in the internet for common composites like FRP, Kevlar, Carbon/graphite etc etc....... It is just that I wanna try it out for various combinations...
Please help me out........
