Strength improvement of adhesively-bonded joints using a reverse-bent geometry
Campilho, Raul; Pinto, A. M. G.; Banea, Mariana D.; Silva, R. F.; Silva, Lucas F. M. daAdhesive bonding of components has become more efficient in recent years due to the developments in adhesive technology, which has resulted in higher peel and shear strengths, and also in allowable ductility up to failure. As a result, fastening and riveting methods are being progressively replaced by adhesive bonding, allowing a big step towards stronger and lighter unions. However, single-lap bonded joints st...
Tensile behaviour of single and double-strap repairs on aluminium structures
Pinto, A. M. G.; Campilho, Raul; Mendes, Isabel R.; Silva, R. F.; Magalhães, A. G.; Baptista, A. P. M.In this work, an experimental study was performed on the influence of plug filling, loading rate and temperature on the tensile strength of single-strap (SS) and double-strap (DS) repairs on aluminium structures. The experimental programme includes repairs with different values of overlap length (LO=10, 20 and 30 mm), and with and without plug filling. The influence of the testing speed on the repairs streng...
Taper angle optimization of scarf repairs in carbon-epoxy laminates
Campilho, Raul; Pinto, A. M. G.; Moura, M. F. S. F. de; Mendes, Isabel R.; Banea, Mariana D.; Silva, Lucas F. M. daThe increasing use of Carbon-Fibre Reinforced Plastic (CFRP) laminates in high responsibility applications introduces an issue regarding their handling after damage. The availability of efficient repair methods is essential to restore the strength of the structure. The availability of accurate predictive tools for the repairs behaviour is also essential for the reduction of costs and time associated to extensiv...
