Carbon fiber reinforced plastic (CFRP) compositelaminates are susceptible for multiple delaminations, which reducethe compressive strength significantly even when the impact load isinsufficient to cause visible damage, the post-impact compressiontest is used widely to assess the relative performance of differentcomposite laminates with different fiber matrix combinations. Inthe present work, CFRP(T300/914) laminates were subjected tolow-velocity impact loading simulating tool drops and runwaydebris. Compression after impact (CAI) tests were performedusing fixtures as per NASA specifications. Results obtainedindicate definite correlation between impact energy, failure strain,and residual compressive strength.
