Summary This paper presents experimental results from tests performed on three types of materials widely used in marine applications: glass reinforced polyester laminate panels produced by hand lay-up, foam core sandwich panels, and filament wound glass and carbon/epoxy cylinders. For all three types of material static tests have been carried out at different scales; results from some scaled impact tests are also reported.
Keywords scale effect, size effect, mechanical testing, impact, sandwich, cylinder.
