Applications:
ASTM ASTM D6641 is a testing standard that determines the compressive strength and stiffness properties of polymer matrix composite materials using a combined loading compression (CLC) test fixture. This test method is designed to produce compressive property data on polymer matrix - mainly used in the Aerospace industry - for the purposes  of research and development, quality assurance, and structural design and analysis. ASTM D6641 can be used to test unidirectional (0° ply orientation) composites as well as multi-directional composite laminates, fabric composites, chopped fiber composites, and similar materials.
