ISO 18352 Compression-After-Impact (CAI) Testing for Carbon-Fibre Composites

← Back to all standards

ISO 18352 is the compression-after-impact (CAI) test method for measuring the residual compressive strength of impacted composite laminates. To match this to your program, talk with our team.

What ISO 18352 Covers

It combines a controlled impact with a subsequent compression test, giving the residual compressive strength that characterizes the damage tolerance of the composite.

Why It Matters

CAI residual strength shows the strength impact of barely visible impact damage, a central requirement for composite aerostructure qualification.
