Transmission spectra of the lowest-order antisymmetric (A0) Lamb wave for adhesively bonded single lap joints are experimentally investigated in a frequency range below 0.4 MHz. Based on theoretical results interference, tangential bond stiffness evaluation method is proposed joints. Aluminum alloy plates with epoxy adhesive different conditions were prepared as specimens. An air-coupled ultras...

There are many advantages to adhesively bonding stiffeners onto aircraft structures rather than using traditional mechanical fastening methods. However there is a lack of confidence of the structural integrity of adhesively bonded joints over time. Acousto-ultrasonic Lamb waves have shown great potential in structural health monitoring applications in both metallic and composite structures. Thi...

The interest in the design and numerical modelling of adhesively-bonded components structures for industrial application is increasing as a research topic. Although on joint failure under pure mode widespread, applied bonded joints are often subjected to mixed loading at crack tip, which more complex than affects strength. Failure these objective predictions through mathematical models, latter ...

Carbon fibre/epoxy composite joints were assembled with Poly-etherether-ketone (PEEK) and Poly-ethylenimine (PEI) films using a co-curing process to prepare single-lap joint specimens. The tested under quasi-static loading conditions at 22 °C 130 fatigue condition. experimental results demonstrated better or comparable structure integrity of the co-cured by PEEK PEI than reference bonded aerosp...
