Original Abstract

The aim of the present work is to compare the effects of a commercial coupling agent, a thermal de-sizing treatment and a plasma polymerization process on the interfacial adhesion of basalt fibres with an epoxy matrix. The different basalt fibres were characterized in terms of surface morphology (FE-SEM) and chemical composition (FT-IR). Fragmentation tests allowed the determination of the interfacial shear strength (IFSS), while the adhesion quality was assessed in terms of critical fragment length and debonding length. The plasma polymerization process was able to produce a homogeneous tetravinylsilane (pp-TVS) coating on the surface of basalt fibres, which resulted in a significant increase in the adhesion between basalt fibre and epoxy resin. The surface roughness of the untreated and treated basalt fibres has been measured by Atomic Force Microscopy (AFM) and the results demonstrate how surface topography can play a significant role in the domain of fiber/matrix interfacial adhesion.
