Composites Part A: Applied Science and Manufacturing

This paper investigates comprehensive knowledge regarding joining CFRP and aluminium alloys in available literature in terms of available methods, bonding processing and mechanism and properties. The methods employed comprise the use of adhesive, self-piercing rivet, bolt, clinching and welding to join only CFRP and aluminium alloys. The non-thermal joining methods received great attention though the welding process has high potential in joining these materials. Except adhesive bonding and welding, other joining methods require the penetration of metallic pins through joining parts and therefore, surface preparation is unimportant. No model is found to predict the properties of jointed structures, which makes it difficult to select one over another in applications. The choice of bonding methods depends primarily on the specific applications. The load-bearing mechanism of bolted joints is predominantly the friction that is the first stage resistance. Hybrid joints performance is enhanced by combining rivets, clinch or bolts with adhesives.

Fatigue Testing of Carbon Fibre Reinforced Polymers under VHCF Loading

A numerical study of damage behaviour in unidirectional Carbon Fibre Reinforced Plastics (CFRP) laminates at different stress ratios is self implemented. The study is conducted using the commercial finite element software ABAQUS employing a layer-based fatigue damage model (FDM) that is capable to regard typical fatigue phenomena like stress redistributions and load sequence effects. A description of the FDM model is provided. At first, the model is calibrated according to experimental findings. Next, a constant fatigue life (CFL) diagram is constructed using actual test data to generate S-N curves for different stress ratios. Finally, different damage behaviour in CFRP laminates is predicted under quasi-static and cyclic loading conditions. The numerical results are discussed and compared to experimental data. The results obtained show the applicability and accuracy of the calibrated FDM.
