| description | In the last decades, structural adhesives have found an increasing use owing to the fact that they, compared to traditional techniques like bolting and riveting, allow more uniform stress in the joint without drilling the parts of the assembly. Moreover, the quality of a bonded joint is strongly linked to the surface treatment used for the adherends. Recently, many studies showed the opportunity to use a CO2 laser for enhancing the mechanical properties of bonded joints in FRP. Nowadays, to optimize their process parameters and texturing represent a necessary step for the growth in this technology. In this work, a numerical study of the effect of laser texturing on end notched flexure (ENF) joints realized in CFRP has been developed. In particular, it is possible to design of the laser texturing for optimizing the mechanical response of bonded joints. |
