Hybrid interspaced and free-boundary aramid fabric back bumper for hypervelocity impact shielding system

Investigating fracture behavior and energy absorption of flexible hybrid biocomposites with soft–hard rubber/biofiller layers and fabric impregnated with matrix under high-velocity impact

“…In the study of multi-layered panels of Kevlar/epoxy and aluminum with different configurations, when an aluminum plate was used on the back of the target (output side), the highest energy absorption was achieved against a highspeed impact [20]. It has also been shown that through fiber impregnation with shear thickening fluids (STF), the high-velocity impact resistance of multilayer composites can be increased [21]. However, depending on the protection and energy absorption required in certain applications, 20 to 50 layers of woven fabric may be required as reinforcement.…”
