    Abstract

    Hybrid panels and angle-laid panels are both efficient in improving capability against ballistic impact. This paper presents a study of 3D angle-laid hybrid fabric panels for ballistic impact with experimental and numerical methods. In experimental part, six different panels were investigated composed of three pieces of UHMWPE woven fabrics (A) and two pieces of Dyneema® UD fabric laminates (B), viz., AAABB, BBAAA, ABABA, A0A30A60B0B45, B0B45A0A30A60, A0B0 A30B45A60. AAABB hybrid panel performs better than ABABA and BBAAA regardless of the fabric angulation. Additionally, angled hybrid panels absorbs more energy than aligned one regardless the fabric sequence in a hybrid panel. In order to detailed analysis, two types of model were established, and they were validated by several experimental tests. The results in simulation part showed that the energy absorption of woven fabric in the front of hybrid panel is 44.5% higher than that of UD fabric in the front while at the rear they go near. In addition, putting UD fabrics at the rear of a hybrid panel highly increases its capability of energy absorption by 50% compared with putting them in the front. Furthermore, the first layer in AAABB panel mainly brings about the result that angled one was better than aligned whereas the third layer in BBAAA mainly results in the similar result.
