Shear through thickness of glass laminate
Shear through thickness of glass laminate
(OP)
Greetings
I know it is an old chestnut - but does anyone have shear strength through the thickness (test) data; for any given multiple layers of csm with an isopthalic resin?
Or any source of such?

RE: Shear through thickness of glass laminate
If you can't do a few short beam shear tests (pretty cheap and not too bad for strength—note, there's no difference between through-thickness shear and interlaminar shear; one is the complement of the other, so the weakest should break), perhaps some micromechanics might give at least an ROM value. The chapter in Eric Greene's book on micromechanics is probably a reasonable place to start. I'd treat it as very approximate, especially if you have to use rough or generic basic polyester matrix properties.
Let us know what you find.

Many thanks for the link: very interesting, and I will study.
I suppose testing is only option.
