Abstract
Fibres anisotropy and their poor adhesion to the epoxy matrix are challenges in developing polymeric epoxy composite for structural applications. Filling of epoxy with reinforcing particles has potential for producing isotropic composites. In this study, epoxy-aluminium particulate composites were developed through combined-stir-techniques. Their interfacial adhesion and microstructural properties were examined. Results obtained indicated bonding of aluminium particles to epoxy through bidentate coordinate bond. Variations observed in the Fourier Transform Infrared spectrographs (FTIR) of both composites’ grades confirm discrepancies in interactions of aluminium micro and nanoparticles with epoxy. A good interfacial adhesion of aluminium nanoparticle with epoxy established by both optical and scanning electron microscopes is an indication of good mechanical performance of the epoxy composites.
