Two liquid composite moulding techniques have been investigated in this study, resin transfer moulding (RTM) and resin infusion under flexible tool (RIFT) for the processing of glass fabricepoxy laminates with 5% nanoaggregates of silica nanoparticles in the epoxy matrix. It has been found that the high fibre fraction reinforcement (V f 50 . 50) filters the silica nanoaggregates resulting in stopping the in plane resin infiltration in RTM right at the beginning of the filling stage. Laminates of lower fibre fraction (V f 50 . 40) were produced successfully by RIFT. Dynamic mechanical thermal analysis (DMTA) and three point bend tests showed that fibre-silica-epoxy composites, processed by RIFT, had higher elastic shear modulus and interlaminar shear strength than conventional fibre-epoxy composites manufactured by the same RIFT process.
