Evaluation of ARALL-4: An Aramid Fiber Reinforced Aluminum

Abstract

ARALL- 4 was evaluated for the following: tensile properties at elevated temperatures; tensile properties in hot/wet conditions; moisture absorption; anisotropy and ballistic impact performance. The tensile properties of ARALL-4 exceed those of 2024-T8 in the longitudinal direction, but they are lower in the transverse direction. ARALL-4 retains excellent tensile properties after full saturation at 95% humidity and at 105 C. The moisture absorption of ARALL-4 is slow. The ballistic impact performance of ARALL-4 is inferior to several commonly used lightweight armor materials including: glass reinforced plastic, KEVLAR laminate, and titanium 6-4. Keywords: ARALL, Tensile properties, Ballistic properties, Moisture absorption, Anisotropy, Laminate.
