Flexural testing of composite materials CompositesWorld

www.compositesworld.com articles flexural Flexural strength and stiffness are not basic material properties. They are the combined effects of a material’s basic tensile, compressive and shear properties. That is, when a flexural loading is applied to a specimen, all three of the material’s basic stress states are induced. Material failure, then, is dictated by which of the three basic stresses is the first to reach its limiting value — that is, its strength.

Flexure testing of sandwich composites CompositesWorld

www.compositesworld.com articles flexure-testing Specimen failure typically is produced at the top of the specimen due to the maximum compression stress, referred to as the flexural strength of the composite laminate. In contrast, the short beam flexure test for solid composites, ASTM 2344 6, uses a span-to-thickness ratio of only 4:1 and three-point loading. This test method is used to determine the short beam strength, defined as the maximum shear stress produced at the mid-thickness of the specimen at failure.
