The preparation of Carbon Fibre Reinforced Polymers (CFRP) surfaces for adhesive bonding has been widely reported.Such reports include laser texturing using both near-infrared (IR) lasers and ultraviolet (UV) lasers.In this report, we present, the first time, findings showing that surface treatment CFRP incoherent UV light, at 254 nm wavelength, can increase strength by 75 % compared to nontreated samples.It is also around 10 stronger than NIR laser-textured samples.However, combination...

Abstract Stainless steel 316L is an austenitic alloy that widely used in varying industries due to its outstanding corrosion resistance, high strength, and ductility properties. However, the wear friction resistance properties are low. Laser surface texturing can improve of material via functionalisation surface. The laser efficiency texture quality defined by material’s parameters. roughness important property having effect on texturing. This paper reports a study influence stainless with...
