ASTM D7137/D7137M — Compression After Impact (CAI) / Compressive Residual Strength of Damaged Composite Plates
ASTM D7137 is the test method for the compressive residual strength of multidirectional polymer matrix composite plates after impact damage, the compression-after-impact (CAI) test. To match this to your program, talk with our team.
What ASTM D7137 Covers
It loads a previously impacted composite plate in compression to failure, giving the residual strength that quantifies how much the impact damage weakened the laminate.
Why It Matters
CAI strength is a key damage-tolerance metric for composite structures, pairing with the impact step to show the strength consequence of impact damage.
