ASTM D7137
The ASTM D7137 Compression After Impact (CAI) Test Fixture is engineered for evaluating the damage resistance and tolerance of composite materials. It provides precise measurement of compressive residual strength properties for multidirectional polymer matrix composite plates. Built with high-strength steel and featuring adjustable edge rails, it ensures secure support and prevents out-of-plane buckling during testing — ideal for aerospace structural design, material development, and quality assurance applications.
Overview
The Compression After Impact (CAI) Test Fixture is designed to measure the compressive residual strength properties of damaged multidirectional polymer matrix composite laminates. Used in conjunction with a pair of compression platens (not included), this fixture is engineered in strict accordance with ASTM D7137/D7137M. It evaluates the damage resistance and tolerance of composite laminates that have previously been subjected to a drop-weight impact event per ASTM D7136/D7136M.
