Carbon fibers used as the reinforcing phase in composite materials have properties in the longitudinal E11f and transverse E22f, for example. I became interested in how mechanical testing is conducted for both the matrix and reinforcing phases. I was able to find the ASTM D3379 standard for determining the properties in the longitudinal direction, but I can't find anything about how the E22f properties are determined.
Can anyone help me figure this out? I would be very grateful!
