An experimental study has been carried out to investigate tensile and bending properties of carbon fiber (CFRE) and glass fiber-reinforced (GFRE) epoxy composites. Three different fiber orientations were applied, 0°, 90° and [0°, 90°]. The laminates were obtained by manual lay-up process. The samples were evaluated by tensile tests according to the ASTM D3039 and bending tests according to the ASTM D790. Experimental results showed that maximum tensile strengths were observed at 0° fiber direction for the both CFRE and GFRE composites. With respect to their tension properties, the CFRE samples had better performance than the GFRE samples, except for the 90° orientation. Three point bending tests proved that in all orientations CFRE composites had better performance, compared to GFRE composites.
