CFRP Damping Ratio?
CFRP Damping Ratio?
(OP)
I am looking for the damping ratios for CFRP composites. The exact ratio is contingent on the orientation and type of fibers but I am just looking for a ballpark number for a quasi-isotropic layup. Any help?





RE: CFRP Damping Ratio?
I have used CFRP tubes for a space structure. For my analysis, I used (with fear since did not know what to expect) a Q of 25 (damping of 0.02) and this led me to conversative accelerations when I compared with the results from a sine test.
Best regards,
Franck
