Abstract

An experimental investigation was conducted to determine wave propagation characteristics, transient strain distributions and residual properties for unidirectional and angle-ply boron/epoxy and graphite/epoxy laminates impaced with silicon rubber projectiles at velocities up to 250ms** minus **1 (820 ft/sec). Tests were conducted at normal and 45-degree oblique impact. Strain signals obtained from surface and embedded strain gages were recorded and analyzed to determine the types of waves, and attenuation characteristics.
