Abstract

Abstract Epoxy was reinforced using aluminum micro and Nano-particles through in-situ polymerisation. Morphological and fracture toughness properties were studied via experiments and models. Results obtained indicated degradation in the fracture toughness of the reinforced epoxy composites above 6% by weight of aluminum microparticle additions. Optical and scanning electron microscopes revealed fracture mechanism by repeated plastic deformation at the crack front, crack growth, deflection and pining. The model indicated that aluminum weight percent (p = 2.48 × 10−5) has a higher significant influence on the composite fracture toughness than aluminum particle sizes (p = 4.12 × 10−5).
