Abstract
The aim of the program on ballistically resistant structures is to develop a fundamental understanding of damage resistance characteristics of protective composite materials of interest to the Army, carried out by a systematic characterization of composite viscoelastic behavior. In the first year of the program, the experimental setup and tooling was organized. Dynamic mechanical analysis (DMA) testing of Kevlar 29 and KM2 was initiated to determine long-term mechanical properties for this material system. RF plasma of allylamine onto Kevlar 29 fiber was carried out to optimize the interfacial surface. The gradient design concept was developed and demonstrated. High and low velocity impact tests were carried out. Post-failure damage assessment was done using optical microscopy and SEM. The objective of modeling of viscoelastic armor was to complement the experimental component so as to obtain a thorough understanding of deformation, energy absorption mechanisms, and failure of viscoelastic armors. Initial work was directed towards identifying the specifics to develop a realistic model and to perform simplified computer simulations based on assumed data. (DTIC)
