ASTM C271 – Density of Sandwich Core Materials

To request a quotation for any test email for a prompt reply

This test method covers the determination of the density of sandwich construction core materials. 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).

Density is a fundamental physical property that can be used with other properties in order to characterize a sandwich core. Most sandwich core structural properties, such as strength and stiffness, are proportional to the density. Obtaining sandwich core density data can be essential for design properties, material specifications, research and development applications, and quality assurance.
