A plausibility argument for angular ultrasonic scattering in fiber-reinforced composites

Author: Patrick H. Johnston (National Aeronautics and Space Administration)

Abstract

NASA is currently pursuing an ultrasonic array-based approach to measure fiber waviness (via local fiber alignment) in fiber-reinforced composites, which is based upon the assertion that ultrasound scatters in many directions from the fibers and that the angular distribution of that scattering can be used to infer the direction of the originating fibers. This paper presents a non-rigorous physical argument for the plausibility of this hypothesis.
