Comparison of coupon tests, mean or B-Value?
Comparison of coupon tests, mean or B-Value?
(OP)
I need your advice in coupon or connections testing to produce material design values in composite field. I am comparing the new prepreg material to the existing one. The set of samples shows a high percentage difference between standard deviation and mean value of the new material and leads to the much lower B-Value as expected. Can I compare both materials using mean value, which is higher for the new material or is it necessary to compare B-values to comply with FAR 25.613?

Can any one guide me on some literature which gives information on how to generate the material and design allowables ( A Basis and B basis ) and their usage to stress group.
Please share the literature if you have..
