Description

Composite materials are finding increasing use in industry due to their attractive strength-to-weight ratio, tailored stiffness, thermal expansion properties, resistance to fatigue and corrosion. Unfortunately, these fiber reinforced polymers are vulnerable to disbonding between successive plies (delaminations) and cracks that propagate parallel to the material fibers. This damage can be induced by relatively low energy impacts, such as a dropped tool. In many instances this damage is not evident from visual inspection and cannot always be detected by X-ray or ultrasonic C-scan examination.

Damage Assessment for Composite Materials Based on Structurally Imbedded Optical Fibers and Image Enhanced Backlighting

Composite materials are finding increasing use in industry due to their attractive strength-to-weight ratio, tailored stiffness, thermal expansion properties, resistance to fatigue and corrosion. Unfortunately, these fiber reinforced polymers are vulnerable to disbonding between successive plies (delaminations) and cracks that propagate parallel to the material fibers. This damage can be induced by relatively low energy impacts, such as a dropped tool. In many instances this damage is not evident from visual inspection and cannot always be detected by X-ray or ultrasonic C-scan examination.
