| The application of the adhesive-bonded CFRP laminates prolonged the durability of steel specimens. This study investigated the influence of carbon fiber reinforced polymer (CFRP) tape reinforcement on the fracture surface characteristics of S235JR carbon steel specimens subjected to uniaxial static tensile load. The steel specimens were reinforced with high strength unidirectional CFRP plates, while one unreinforced specimen served as a reference. To evaluate the topographical and morphological features of all fracture surfaces the 3D optical profilometry and scanning electron microscopy had been used. The chosen ISO 25178-compliant roughness parameters were cal- culated, including height, functional, and functional volume parameters, as well as non-standard descriptors, such as furrow geometry and texture isotropy. The results indicate that height parameters are not significantly affected by the presence of CFRP, since they are sensitive to localized anomalies. In contrast, the functional and functional volume parameters revealed notable differences: reinforced specimens showed lower values of peak material vol- ume Vmp and core void volume Vvc along with reduced plastic deformation and more localized fracture behavior. Additionally, peak material portion Smr1 and valley material portion Smr2 were slightly higher in the unreinforced specimen, indicating more homogeneous plastic deformation. Analysis of furrow geometry and texture isotropy revealed that unreinforced steel exhibited ductile fracture with high furrow density and isotropic texture, while CFRP reinforcement introduced anisotropy texture and features associated with mixed ductile-brittle fracture. The presented findings demonstrate the significant impact of composite on fracture mechanisms and surface morphol- ogy of the reinforced specimens. |
