Abstract
The currently used high-performance fiber materials for soft body armor have very low surface friction and this has become an issue in the effectiveness of ballistic energy absorption. In this study, non-polymerizing reactive plasma gas N 2 and chemical vapor (CH 3) 2Cl 2Si were employed to modify Kevlar fabric surface for the application of ballistic impact material. Scanning electron microscopy observations yield information about the surface effect of the fabrics after plasma treatment. The surface morphology of the treated fabrics was studied. Energy-dispersive X-ray analysis was used to analyze the surface chemical properties of the treated samples. The yarn pulling-out test shows that the resistance to pulling out yarns from fabrics plasma-treated treated with N 2 and (CH 3) 2Cl 2Si plasma-treated fabric is increased 18% and 300% respectively, compared with the untreated Kevlar fabric. Finite element simulation results revealed that fabric with a higher surface coefficient of friction performs better in ballistic energy absorption. © The Author(s) 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
