Studying the flexural characteristics of the epoxy reinforced by al and cu particles

الملخص EN

In this research the flexural characteristics of the composite beam made from epoxy reinforced by (Al) and (Cu) particles with different volume fraction (3 %, 6 %, 9 %, 12 %, and 15 %) where studied.

The results show that the modulus of elasticity, the flexural strength and maximum shear stress increase with increasing the volume fraction of the reinforced particles of (Al) and (Cu), while the deflection decreases with the increasing the volume fraction.

And the results show that the reinforcement with Cu particles give the best results than the reinforcement with Al particles.

The maximum values of the modulus of elasticity, flexural strength and maximum shear stress for the epoxy reinforced by Cu particles was (4600 MPa.) ,(1535 MPa.) and (18.1 MPa.) respectively at the volume fraction (Vf =15 %).
