Ultimate strength of composite material is related to normalized stress-wave factor, a measure of attenuation of stress wave. New portable ultrasonic inspection instrument measures strength of composite materials. New commercial instrument has similar specifications to prototype developed at Lewis Research Center. Device may ultimately help to reduce energy consumption and improve efficiencies of vehicles by allowing use of composite materials to their full potential in critical application areas.
