Abstract

Ultrasonic attenuation and velocity in graphite/epoxy composites damaged by real and simulated laser radiation were measured. The measurements were carried out in a water-tank ultrasonic testbed constructed to study the elastic properties of samples subjected to carbon dioxide laser radiation at a number of different scan rates. Parallel simulation studies were carried out on samples subjected to temperatures high enough to cause pyrolysis. The ultrasonic measurements were made in the 1 to 5 MHz range for varying incidence angles. Damage manifested itself in differing degrees of porosity depending on the irradiation intensity. Both attenuation and velocity were sensitive to damage. The purpose of the study was to assess possible effects of laser weapons on aerospace structures.
