    Evaluation of the Mechanical Properties of Microcapsule-Based Self-Healing Composites by Liberata Guadagno, Marialuigia Raimondo, Umberto Vietri, Carlo Naddeo, Anja Stojanovic, Andrea Sorrentino, Wolfgang H. Binder

    Published 2016-01-01
    “…The experimental results show that the mechanical properties of the self-healing systems are mainly determined by the chemical nature of the epoxy matrix. In particular, the replacement of a conventional flexibilizer (Heloxy 71) with a reactive diluent (1,4-butanediol diglycidyl ether) allows obtaining self-healing materials with better mechanical properties and higher thermal stability. …”

    ANALYSIS OF THE VARIATION OF THE ROUGHNESS OBTAINED DURING TURNING WITH TRANSVERSE FEED DUE TO THE MODIFICATION OF THE FUNCTIONAL GEOMETRY OF THE CUTTING TOOL by Mădălin TOMESCU, Ionela Magdalena ROTARU

    Published 2023-05-01
    “…The quality of the surface of a part is a very complex notion and includes two aspects: the geometry of the superficial layer, which determines the deviations of the real surface from the theoretical surface and the roughness (micro-irregularities) of the real surface and the condition of the superficial layer of the processed surface from a physical point of view (degree of deformation, residual stresses, thermal, chemical, thermochemical treatments, etc.). From the point of view of machining by chipping, the first aspect is very important and in particular the surface roughness. …”
