Ballistic efficiency of hybrid laminates based on aramid and UHMWPE prepregs

Popis výsledku v původním jazyce

The work is focused on comparison of ballistic efficiency of homogeneous laminates consisting of one type of prepreg based on aramid or UHMWPE and ballistic efficiency of hybrid laminates consisting of combitation of chosen prepregs layered in different order. For preparetion of hybrid laminates the two types of aramid prepregs and two types of UHMWPE prepregs were chosen. The laminates were subjected to ballistic testing by fragment simulating projectile FSP G5 and their ballistic efficiency was evaluated by determination of ballistic limit V50. For more complex assessment of tested laminates with regard to ballistic efficiency and also their areal weight, the coeficient K, which is defined by quotient of V50 and areal weight, was determined for each laninate and then compared. Besides the ballistic efficiency the coherence of laminate layers after pressing and after shooting was also observed.
