AC-130H Gunship Armor Upgrade Project (Technical Report

The developed Boron Carbide/Aluminum based materials are a promising alternative for the use in lightweight armor application. The advantage of B4C/A1 composite over the traditional metal armor is its ballistic limit of 80 to 90% of that for hot pressed B4C, thus similar to ceramics such as A1N or SiC.APPLYING STEINBERG'S MODEL TO THE HUGONIOT ELASTIC Jan 01, 1992 Plate impact experiments were performed on boron carbide specimens, having different porosities, in order to measure their Hugoniot elastic limit (HEL) values.
