Flexural Properties of Sandwich Constructions - ASTM C 393

As sandwich constructions are increasingly being used with the for high-strength, light-weight components, standard test methods are being developed and used to determine critical properties and strength assessments. C393 covers the test procedures to determine many of these properties in a flatwise flexure configuration. The test consists of three and four-point bending of the samples with load and deflection measurements. Many different properties can be determined from a single set of tests, such as sandwich flexural stiffness, the core shear strength and shear modulus, and facing strength. Tests to evaluate core shear strengths may also be used to determine core-to-facing bond strength.
