The Behavior of the Advanced Materials for Blast Energy Absorption under Low and High Velocity Load

Abstract:

This paper describes experimental investigation on the response of new advanced materials to low and high velocity load. Foams were designed using two types of porous lightweight spherical raw materials with dimensions of 30-100 μm, combined with polymer matrix. Prism shaped specimens were prepared and loaded to obtain physical-mechanical parameters bulk density, compressive and flexural strength under quasistatic load and impact strength. The load-displacement data were captured. The slab specimens were prepared of selected materials, covered with a layer of ballistic laminates on both surfaces to form the sandwich element and were subjected to the blast load of 100 g Semtex 1A from a distance of 10 cm. Blast energy absorption was measured on test rig STAND T0-B according to methodology M-T0-B VTÚO 10_09.
