Summary of Test
The ASTM C365 standard covers the determination of compressive strength and modulus of sandwich cores. Results from this test method can be used for sandwich core structural design and development applications, material specifications, and quality assurance. During the test, a uniaxial compressive force normal to the facings of the sandwich core is applied utilizing a universal testing machine equipped with compression platens.
Before conducting ASTM C365, it is important to read the entire specification in the relevant ASTM publication.
Recommended Equipment
Testing Procedure
- Use conditioned square or circular samples in compliance with ASTM C365, to be used only once.
- Place the specimen on the lower platen, accommodating the displacement transducer or compressometer as necessary. Make sure the sample is centered between the platens.
- Apply a compressive load to the specimen at the specified rate until failure. The suggested standard displacement rate is found in the testing standard.
- Adjust the speed of the testing machine so that failure occurs within 3-6 minutes of testing.
- To obtain best results, perform testing in environment that the samples were conditioned in.
