Abstract
A full set of elastic constants was determined/estimated for two sandwich composite skin laminates. Out-of-plane compression and shear specimens were cut from skin laminates bonded together to avoid making thick laminates. The approach gives relatively low scatter for the elastic constants and little influence from the bonds as judged from finite element analysis.
