Initial results for detection of disbonds in the hydrofoil structure | 08-DEC-10

The work carried out by TWI on a representative hydrofoil structure look promising. The initial results show that it is feasible to detect disbonds in the composite hydrofoil structure. The built-in defects in the bond line between GFRP and CFRP (spar box) structure were inspected using ultrasonic guided waves. The results show that the disbond can be detected. However, the techniqe needs to be developed further but the early results look promising.
