Abstract

This paper presents an experimental and numerical study to evaluate the ballistic performance of E-glass/epoxy and S2-glass/epoxy composites. Composite materials were produced by vacuum assisted resin infusion molding method. All the specimens were then subjected to ballistic impact tests by gas-gun system. Residual velocities were measured by high-speed camera for different velocities. Ballistic limits of all composites were obtained by curve fitting residual velocity-impact velocity data. It was found that S2-glass/epoxy composite has a higher ballistic limit than E-glass/epoxy. S2-glass/epoxy has also more specific absorbed energy and absorbed energy density than E-glass/epoxy. Numerical results were in good agreement with experimental results.
