NONDESTRUCTIVE EVALUATION

Nondestructive methods are used to detect and characterize flaws in composite materials and to insure the integrity of composite structures in service. Nondestructive evaluation (NDE) methods used include:

  • Optical
  • Radiographic
  • Acoustic emission
  • Ultrasonic


X-radiographs of fatigue damage in [0/902]s carbon/epoxy
laminate at various fatigue numbers of cycles


X-radiograph of [0/-45/90/45]2s carbon/epoxy plate after
falling weight impact

 


Ultrasonic C-scan and B-scans through various sections of
impacted carbon/epoxy laminate

 


Ultrasonic 3D images of impact damage in composite laminate
