The deflectomer protrudes through a hole machined in the center of the specimen. The test method investigates how the core materials, methods of fabrication, core geometry, core density, loading process, and the loading process affects the compressive strength of the honeycomb material.

Flatwise Compressive Properties by ASTM C

These mechanical properties can, in turn, be used in design purposes, material specifications, research and development applications and quality assurance. Select from list below: Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb — stabilized or unstabilized.

Inspection Validating the specifications, value and safety of your raw materials, products and assets. Combining values from the two systems may result in non-conformance with the asrm.

Flatwise Compressive Properties by ASTM C365

We are confident that we have what you are looking for. Certification Formally confirming that your products and services meet all trusted c3655 and internal standards. Deformation data can be obtained, and from a complete force versus deformation curve, it is possible to compute the compressive stress at any applied force such as compressive stress at proportional limit force or compressive strength at the maximum force and to compute the effective modulus of the core.

Need help or have a question? Install the conditioned specimens if required into the loading platens on the C635 Test Machine and initiate at a specified grip separation significant enough to produce failure within 3 to 6 minutes. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

ASTM C / CM – 16 Standard Test Method for Flatwise Compressive Properties of Sandwich Cores

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Subscription pricing is determined by: Send us a request Wilton UK: Add to Alert PDF.

Acceptable core material forms include material with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.

The sandwich core will be subjected to a uniaxial compressive force normal to the plane of the facings as the core will be placed in a structural sandwich construction.

Permissible core material forms include those with continuous 3c65 surfaces such as balsa wood and foams as well as those asttm discontinuous bonding surfaces such as honeycomb. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters ast, 56 mm to mm 2. Combining values from the two systems may result in non-conformance with the standard.

It is customary aerospace industry practice to determine compression modulus only when using stabilized specimens. From flatwise compression results the following calculations can be made:
