Graphite composites are vulnerable to damage resulting from impact by hard objects with low velocity. The effect of this impact causes severe internal damage to the structure with little or no visual surface indications. Various impact damaged panels were nondestructively tested to assesss damage. A field test was developed using a portable ultrasonic thickness tester. (Kursetz)
