Abstract In this study, non-hybrid and hybrid (Kevlar, carbon glass) fabric epoxy composite laminates were fabricated with different stacking sequences by hand lay-up followed hot-compression molding. Experimental tests conducted to investigate tensile, flexural, hardness characteristics. It was found that the sequence did not significantly affect tensile strength values of composites; however,...

Abstract A theoretical energy-based model to capture the ballistic response of sandwich structures made composite material peels and a crushable foam core was developed. The based on wave propagation theory it split in six stages with their corresponding energy-absorption mechanisms. division physical interpretation perforation process involving reasonable hypotheses simplifications. analysed a...

The use of high-modulus ceramic materials under conditions simulating the screen protection space objects from damage by fragments man-made debris is considered. introduction an aluminum jet at a speed ~10 km/s into barrier located behind brittle material screens was experimentally studied. A comparative analysis parameters residual cavity in made it possible to reveal effect structural rearran...
