Abstract

In the present study, an experimental investigation of the behavior of sandwich plates with different core densities and different surface plates under shock loads was carried out with the help of a shock tube setup. EPP foams of different densities were used as core material. Aluminum and continuous Carbon fiber reinforced thermoplastic composite plates are used as surface plates. The hot melt EVA adhesives were applied for joining foam and surface plates. The shock pressure was measured with high precision piezoelectric pressure gauges. The speed, acceleration of the shock pressure wave, and the impulse and momentum values affecting the sandwich panels were calculated. The results are concluded by comparing the deformations and damage patterns of the sandwich panels depending on the core density and the type of surface plates.
