Thermosetting polymers are very popular in the automotive and aeronautic industry, in particular epoxy resin is widely used as matrix thermoset in carbon and glass  fibre reinforced composites. The properties of these epoxy-based polymers can be improved with the addition of particulate or small fibre materials in order to construct a lightweight material with enhanced mechanical and structural response. This work aimed to manufacture and characterize epoxy resin reinforced composites with iron (II, III) oxide (magnetite, Fe3O4) in amounts of 0.25, 0.5 and 1 wt%, and 2 and 4 wt% of fumed silicon dioxide (silica, SiO2). Mechanical properties were investigated by three-point bending flexural test, fracture toughness, flexural stress relaxation. In addition, apparent porosity, apparent density and Differential Scanning Calorimetry tests were performed. The results showed that the addition of Fe3O4 does not contribute significantly to the improvement of mechanical properties. However, fumed SiO2 promotes a considerable improvement in the mechanical properties.   Keywords: Composite, epoxy resin, Fe3O4, SiO2, mechanical properties


The effects of micro cellulose reinforcement on the mechanical properties of epoxy composites were investigated. Micro cellulose were extracted from Hibiscuss sabdariffa fibers using the steam explosion technique and repeated chemical treatments. Reinforcing of epoxy resin with micro cellulosic fibers was done in particle form. Tensile, hardness and impact results revealed that mechanical properties of micro cellulose reinforced composites increases for 10%, 20% and 30% fiber loading and then decrease for 40% loading. Composite with 30% of micro cellulose enhanced the overall mechanical properties of composite, due to the enhanced fiber-matrix adhesion and micro cellulose reinforcement.
