Getting the in-plane shear modulus G12 of a weave composite...
(OP)
Hey guys, I'm trying to get G12 of a cured composite. The fibers are weave, so is there a special formula I can use to find G12 (Huber's Formula?).. or is it only determined experimentally. Let's assume there's no data sheet for the material, and currently I have E1 (which equals E2) and poissons...

However, the G12 for most carbon fiber epoxy composites (uni tape and fabrics) at room temperature is ~ 0.7 msi

Do you have a source for G12 being roughly .7 msi?
