Thank you for your reply!
I don't quite understand where carbon fiber manufacturers get these values for E22f. Are these derived using some chemical methods, or do they also conduct mechanical testing? Sometimes it's necessary to know E22f to use it in micromechanical models.
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...
