On longitudinal compressive failure of carbon-fibre- reinforced polymer: End crushing for highly orthotropic specimens; support s-concentration; specimen tolerances critical.
Alignment; high data averages and low scatter; long-standing test fixture Disadvantages: Link to Active This link will always route to the current Active version of the standard. My presentations Profile Feedback Log out.
ASTM D test procedure: Within the text the inch-pound units are shown in brackets. No specimen tapering required; better results with cross-reinforced materials Disadvantages: The chamber is designed to allow the test mounts from the base and crosshead of the Instron to pass through the top and bottom of the chamber.
Auth with social network: High strain rate characterization of unidirectional carbon-epoxy IM in transverse compression and in-plane shear via digital image correlation Pedro. Large specimens materials expense ; failure must occur in compressive face sheet. Michael Starbuck, Pakal Rahulkumar, Raymond.
