Lacquer Reveals Impact Damage in Composites
Abstract
Brittle lacquer unveils effects normally visible only by ultrasonic inspection. Laquer coating measures spread of cracking and delamination in graphite/epoxy panels subjected to cyclic compression loads after impact damage. Test specimen is coated with lacquer on side opposite surface at which projectile will be fired. Spalled area shows effect of impact without removing specimen from test fixture.
