The quality of a bonded joint is strongly linked to the surface treatment used for the adherends. Recently, many studies have 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, an experimental and numerical study of the effect of laser texturing on end notched flexure (ENF) joints realized in CFRP has been developed. The laser texturing showed an important effect on the mechanical resistance of ENF joints, with an increase of at least 76% respect untreated ones. The numerical results showed a good agreement with the experimental ones. Therefore, it is possible to design of the laser texturing for optimizing the mechanical response of bonded joints.

Abstract
The quality of a bonded joint is strongly linked to the surface treatment used for the adherends. Recently, many studies have 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, an experimental and numerical study of the effect of laser texturing on end notched flexure (ENF) joints realized in CFRP has been developed. The laser texturing showed an important effect on the mechanical resistance of ENF joints, with an increase of at least 76% respect untreated ones. The numerical results showed a good agreement with the experimental ones. Therefore, it is possible to design of the laser texturing for optimizing the mechanical response of bonded joints.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
