Parametric investigations of mechanical properties of nap-core sandwich composites

Ha, Giap X.; Marinković, Dragan; Zehn, Manfred

The focus of this paper lies on the sensitivity of the nap-core sandwich – a novel kind of structural composite – to changes of its parameters. First, the fabrication, properties, and applications of the nap-core sandwich are briefly presented. This is followed by consideration of the sandwich composite's mechanical behavior. Finite element based simulation is applied to perform the parametric investigations. The height of the nap-core and the thickness of its knitted fabric as well as the face sheet of the sandwich are changed in order to investigate the dependence of the general mechanical properties of sandwich composites on those parameters. Experiments are used to validate the simulation results. The conducted investigation provides valuable information for the design of nap-core sandwich composites.
