In this research the influence of submicron zinc oxide and silicon dioxide particles on mechanical, thermo-mechanical properties of epoxy matrix composites reinforced with glass fibres was investigated. Composites were fabricated using hand lay-up method. Materials contained 39-41 wt.% of glass fibres. The bending tests, dynamic mechanical analysis and tribological tests were performed on each group of composites and also for reference samples (without submicron particles). The results showed that 2 wt.% addition of silica or 4 wt.% of zinc oxide to epoxy matrix improved the flexural strength and flexural modulus of composites. DMA investigation showed increasing of storage and loss modulus, for mentioned content of submicron particles. It can be attributed to the good dispersion and interaction between particles and polymer matrix. It was also found that addition of submicron silica particles increased of abrasion resistance.
