ASTM D6641 Standard Test Method for Compressive Properties of Polymer Matrix Composite Materials Using a Comined Loading Compression (CLC) Test Fixture
This method is performed by applying combined end-loading and shear-loading using a combined loading compression fixture. This standard is designed to analyze the compression properties of polymer matrix composite laminates employing either multidirectional or unidirectional fibers or other comparable materials.
The specimen is placed inside the test fixture and bolts tightened to a specific torque. It is then placed within between two platens in the testing machine and a strain measuring device may be attached. The specimen is then compressed to failure.
Laminate compressive strength, laminate compressive modulus, compressive Poissonâ€™s ratio by chord method
Test frame, CLC test fixture, compressometer or strain gauges
