ASTM C364 Test Guide: Compression Testing for Composites
CompressionGrind the loaded ends of the sandwich panel flat and perpendicular to the facings within 0.02mm to eliminate edge stress…
-
ASTM C365 Test Guide: Compression Testing for Composites
CompressionAlways use a direct-contact deflectometer setup to measure core deflection; crosshead travel includes platen-seating errors.
-
ASTM C393 Test Guide: Flexural Testing for Composites
FlexuralAlways place the specified elastomer pads between the anvils and the panel to spread out high localized line loads.
-
ASTM D2344 Test Guide: Shear Testing for Composites
FlexuralInspect specimens under a microscope post-test; you must verify that the failure was true interlaminar shear and not top-edge crushing.
-
ASTM D3410 Test Guide: Compression Testing for Composites
CompressionAlways bond back-to-back strain gauges on every specimen to actively compute and document real-time out-of-plane bending percentages.
-
ASTM D3518 Test Guide: Characterization Testing for Composites
ShearYou must gather both longitudinal and transverse strain simultaneously; in-plane shear strain equals axial strain minus transverse strain.
-
ASTM D5379 Test Guide: Shear Testing for Composites
ShearAlways apply two cross-axial strain gauges mounted at $pm$45 degrees relative to the loading axis within the notch zone to…
