Compressive Strength of Sandwich Cores using ASTM C365.
The test method is used to determine compressive strength in the direction the core would be placed in a structural construction. Core materials applicable include continuous (foams) and discontinue bonding surfaces (honeycomb) – stabilized or unstabilized.
Test procedure: Install the conditioned specimens (if required) into the loading platens on the Universal Test Machine and initiate at a specified grip separation significant enough to produce failure within 3 to 6 minutes. The standard speed is 0.50 mm/min [0.020 in/min].
Specimen size: Five specimens tested at thickness.
Data: From flatwise compression results the following calculations can be made:
