Ultrasonic evaluation of reinforced plastics
Bursts of ultrasound from 1.5 to 2.1 and of few microseconds duration were transmitted through unreinforced polyester and epoxy castings and through laminates of glass fiber reinforced fabric, laminates with varying amounts of entrained air, and laminates with different finishing treatments; velocity of pulses was proportional to ratio of glass to resin; attenuation of signal was proportional to amount of entrained air; conclusions on quality.
