Abstract
The incorporation of nano or micro ceramic particles into fibre reinforced composites (FRC) to enhance their stiffness and durability has been widely investigated. This mechanism has been attributed to the increase in stiffness of the polymeric matrix phase and shear strength of FRCs due to the presence of particles at the interlaminar regions. In order to elucidate such effect, hybrid single-lap joints consisted of ceramic particles and glass fibre reinforced composites were evaluated to better assess the mechanical interlocking effect provided by silica and cement inclusions. A full factorial design (23) was performed to identify the effect of the type of particle (silica and cement), particle weight fraction (2.5 and 5Â wt%) and glass fibre grammage (200 and 600Â g/m2) on the apparent shear strength and adherent strength of single-lap joints under tensile loading. The ceramic particle inclusions led to increased apparent shear strength and adherent strength. The inclusion of 5Â wt% ceramic particles into 600Â g/m2 cross-ply glass fibre composites enhanced both adherent and apparent shear strengths.
