ASTM D5467 / D5467M-97Standard Test Method for Compressive Properties of Unidirectional Polymer Matrix Composite Materials Using a Sandwich Beam
ASTM D5467 is a test method that determines the in-plane compressive properties of polymer matrix composite materials reinforced by high-modulus fibers in a sandwich beam configuration. The composite material forms are limited to continuous-fiber composites of unidirectional orientation. ASTM D5467 introduces compressive load into a thin skin bonded to a thick honeycomb core with the compressive load transmitted into the sample by subjecting the beam to four-point bending.
Before conducting ASTM D5467, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
