Howdy,
I'm a little confused about the correlation between carbon fiber grades and the elastic modulus of the final product. This article from Rock West indicates that standard modulus starts at 33 Msi, with ultra-high modulus at 65 Msi. However, the tubes I'm seeing all seem to have elastic modulus well below 33 Msi, such as this ultra-high modulus tube listed at 26.64 Msi. I thought this might be a matter of the fibers vs. the final product or the type of loading the tube undergoes, but I haven't found any information to that effect. Could y'all shed some light on this for me?
