One-dimensional wave pulses in steel-epoxy composites

Experimental studies of wave propagation, attenuation and dispersion have been conducted in order to establish criteria for predicting energy-transfer and absorption properties of uniaxially reinforced steel-epoxy resin composites in the direction of the reinforcement. Laboratory-prepared long-bar specimens were fabricated for test purposes with small-amplitude waves introduced in specimens of varying wire size and volume percent of reinforcement, by impact with pure-epoxy rods projected from an air gun. Impact velocities were sufficiently small that the structural integrity of composite-bar specimens was maintained. Principal results are wave speeds, wave forms, attenuation and dispersion data for several geometries, prediction techniques based on properties of constituent material, and comparisons with wave behavior in the pureconstituent materials.
