From flatwise compression results the following calculations can be made: Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. It is customary aerospace industry practice to determine compression modulus only when using stabilized specimens. The test procedures pertain to compression in this direction in particular, but also can be applied with possible minor variations to determining compressive properties in other directions.
Standards can be obtained from appropriate standard authorities. Historical Version s – view previous versions of standard. Select from list below: The standard speed is 0.

Permissible core material forms include those with continuous bonding surfaces such as balsa wood asym foams as well as those with discontinuous bonding surfaces such as honeycomb. The results of ASTM C, flatwise compressive strength and modulus, are fundamental mechanical properties ast sandwich cores that are used in the design of sandwich panels.

This standard is also available to be included in Standards Subscriptions. 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. Combining values from the two systems may result in non-conformance with the standard.

ASTM C / CM – 16 Standard Test Method for Flatwise Compressive Properties of Sandwich Cores
Continuous bonding surfaces — minimum facing area shall be mm 2 1. 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.
Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. These mechanical properties can, in turn, be used in design purposes, material specifications, research and development applications and quality assurance.
These material properties are determined for the design purposes in a direction normal to the plane of facings as the core would be placed in a structural sandwich construction. You may delete a document from your Alert Profile at any time.
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.
ASTM C/CMa – Standard Test Method for Flatwise Compressive Properties of Sandwich Cores
This measures the deflection of the specimen and is used to calculate strain throughout the test. We have no amendments or corrections for this standard. Combining values from the two systems may result in non-conformance with the standard.
