Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. Touchstone Research Laboratory, Ltd.

Sandwich constructions are increasingly being used as high-strength, light-weight components, and therefore, standard test methods are being developed and used to determine critical properties and strength assessments. Select from list below: The test method ASTM C determines flexural strength, core shear strength and facings compressive and tensile strengths in the direction the core would be placed in a structural construction.

ASTM C Flexure tests on flat sandwich construction may be conducted to determine the sandwich flexural stiffness, the core shear strength and shear modulus, or the c3993 compressive and tensile strengths.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C The standard loading configuration is a 3-point configuration with a support span of mm [6. Combining values from the two systems may result in non-conformance with asfm standard.

Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb. Inspection Validating the specifications, value and safety of your raw materials, products and assets. ASTM Asm testing covers the test procedures to determine many of these properties in a flatwise flexure configuration.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Validating the specifications, value and safety of your raw materials, products and assets. Wider load pads with rubber pads may assist in distributing the loads.

ASTM C determines the core shear properties of flat sandwich constructions subjected to flexure in such a manner that the applied moments produce curvature of the sandwich facing planes. Install the conditioned specimens if required into a 3-point or 4-point loading fixture on asfm Universal Test Machine and initiate at a specified grip separation significant enough to produce c3993 within 3 to 6 minutes.

Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb.
