ASTM D6641 / D6641M - 16e1Standard Test Method for Compressive Properties of Polymer Matrix Composite Materials Using a Combined Loading Compression (CLC) Test Fixture
The ASTM D6641 test method determines compressive properties of polymer composite materials by applying combined end-loading and shear-loading using a combined loading compression (CLC) fixture. ASTM D6641 is designed for polymer matrix composite laminates which contain at least one 0˚ ply, but other materials can also be tested. The test fixture is designed to provide a combined loading to the unsupported center 12 mm (0.5 inch) gauge length of the specimen.
Before conducting ASTM D6641, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
