Failure Investigation of Layered LFT SB1plus Package after Ballistic Tests for Level IIA
The main objective of this study focuses on designing and testing body protection systems using advanced materials based on aramid fibers, for high impact speeds of up to 420 ± 10 m/s. Ballistic applications of aramid fiber-based composites mostly include soft body armors. The investigation of the f...
