Abstract
This paper focuses on the study of the hybrid laminated composite made from Kevlar and Dyneema fabric. The aim is to achieve a flexible and protective shield. Ballistic impact tests have been done on the both the Dyneema and Kevlar fabrics and we can absorb that the Kevlar fabric can absorb more energy than the Dyneema fabric where the areal density plays the important role. When the areal density of the Kevlar fabric panel reached approximately 1.42 kg/m2, we can see they began to outperform the Dyneema equivalent in terms of the energy absorption. As a result, hybrid panels combining the two types of fabric were created, and these panels were found to have a higher specific energy absorption than single phase panels. In comparison to panels manufactured un reverse order, positioning of the Kevlar fabric layer close to the impact face and the Dyneema fabric layer towards the back face resulted in a ballistic performance gain of roughly 16% percentage.
