Abstract

The primary aim of this paper is to create artificial inter-laminar kissing bond-like defects in CFRP panels for ultrasonic inspection. Carbon fibre reinforced polymer structures pose a unique problem, as unlike metal-tometal bonds (single bond line) carbon fibre reinforced polymer composites have multiple bond lines (between each laminate layer and between the individual carbon fibre bundles). This increases the number of locations for kissing bonds and other defects to lie. Published works look at bonding defects in joints (lap joints, and solidsolid bonding). This paper looks at inter-laminar bonding. A number of samples are created and attempts are then made to detect these kissing bonds using ultrasonic techniques. Further investigation into contaminants for artificial defect creation is advised and destructive verification of the kissing bond samples is still required.
