The extensive use of adhesives in many structural applications in the transport industry and particularly in the aeronautic field is due to numerous advantages of bonded joints. However, still many researchers are working to enhance the mechanical properties and rheological performance of adhesives by using nanoadditives. In this study the effect of the addition of Multi-Wall Carbon Nanotubes (...

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...

The thermal loading during the curing process of an adhesive-bonded joint induces residual stresses in joint, thereby affecting its performance. problem becomes worse case a multi-material involving varying coefficients expansion (CTE) for different parts. A novel approach was developed to model properties automotive grade structural adhesives heat process. material divided into two components:...

This paper proposes a new lap-joint configuration, the so-called Orion beam. The setup is composed of two thin beams connected by three bolted joints with contact patches on each connecting bolt. beam suggests an assembly in which there are bolts dedicated to “static” functions guarantee structural integrity and those that perform “damping” increase energy dissipation due frictional contact. In...

The critical role played by adhesive bonds in lap joints is well known. A good knowledge of the mechanical properties of adhesive bonds in lap joints is a prerequisite to the design and reliable prediction of the performance of these bonded structures. Furthermore, the lap joint may be subject to high-temperature environments in service. Early detection of the degree of thermal degradation in a...
