Abstract

In the presented study, epoxy resin-based syntactic foams were obtained by reinforcing with glass bubbles and solid glass spheres. Sandwich materials were produced by combining the syntactic foams with different properties obtained in a functionally graded structure to improve absorption properties under shock and impact load. The performance of the sandwich materials produced under shock load and medium-speed impact load was experimentally investigated and examined. Experiments were carried out in the laboratory using the shock tube test set-up and gas accelerated horizontal impact test set-up in AMAMRG Lab. Impact load profiles and damage shapes were obtained in impact experiments. In shock tube experiments, shock pressure profiles and displacement variations obtained during the impact of the shock load were measured from the back surface of the sandwich plate. Moreover, the permanent displacements formed after the explosion were measured. Three different core structures were also developed and comparatively examined.
