The influence of fillers loading rate on the tensile behaviours (tensile strength, Young Modulus, tensile energy, tensile strain and Stress at LOP) of reinforced epoxy composites were investigated in this research. Both filler materials (OBPS and SD) where treated with 5(w/v)% Sodium hydroxide solution for 1 hour at ambient temperature of 27±3°C. The composite samples were prepared with five different volume (10, 15, 20, 25 and 30 vol%) of OBPS and SD in the ratio of 1:1, using the hand lay-up method. All the composite samples were prepared and tested according to ASTM standards, using the Universal Testing Machine. Results from this present research showed that the fillers loading had significant (P ≤ 0.05) effect on all the tensile behaviors investigated. In addition, the results showed that all the five tensile behaviours of the samples increased gradually with increase in fillers loading. The tensile strain increased by 53.18%, as the fillers loading increased from 10% to 30 vol.%.in addition the tensile strength increased from 7.86 to 27.47 MPa, while the Young modulus increased from 668.4 to 1235.93 MPa. Results obtained from this study can be helpful in the production of composite boards for industrial applications.
