Foams comprising of ∼60 vol% hollow glass microspheres (GMS) in an epoxy matrix were modified by the addition of milled carbon fibre (MCF). Weight ratios of up to 30% MCF:GMS were used. The tensile modulus of the foams increased from 3.36 GPa up to 4.82 GPa with the addition of 30% weight ratio of MCF. The tensile failure strength of the syntactic foam decreased with low loadings of MCF, which is attributed to low load transfer capacity among the fibres due to poor fibre population. The tensile failure strength recovers when more MCF particles are added. The fracture energy of the syntactic foam showed an increase of 217%, from 182 J/m2 to 396 J/m2, due to the addition of 30% weight ratio of MCF. Toughening mechanisms were identified as crack deflection, debonding and subsequent plastic void growth, and fibre pull-out.
