Abstract

A commercially available core-shell rubber nanoparticle dispersion (CSR) was introduced into a carbon fibre/epoxy composite with the primary aim of enhancing the composite's fracture toughness. The dispersion and permeation of the CSR particles through the thickness of the laminate was examined by scanning electron microscopy (SEM). The flexural and compression after impact (CAI) properties of the CSR toughened laminates were investigated. The residual compressive strength values increased between 6-26% with the incorporation of 1 to 3 weight% of CSR. The glass transition temperature of the composite, obtained from dynamic mechanical analysis (DMA), remained unchanged up to 3% loading of CSR. The transverse flexural strength of the composites showed a drop between 6-14% with the addition of 1-5 weight% of CSR. The results indicated that addition of a small amount of CSR (between 1-3 weight%) in the resin formulation might be beneficial to enhance the fracture toughness of carbon fibre/epoxy composites without any concomitant adverse effects on other important properties.
