I. INTRODUCTION
Tensile Test
The Tensile test is a destructive test process that
provides information about the Tensile strength, % of
Elongation, yield stress and toughness etc. In this work, the
tensile properties of the developed composites were
obtained using 25 kN servo-hydraulic UTM. The ASTM E8
standards dimensions for conducting tensile test.
There changed into a decrease within the % Elongation values after the addition of CESs to the Mg-Al2O3, Eggshell matrix.
This the Mg-Al2O3, un carbonized Egg shell is 6.78% Elongate and Mg-Al2O3,carbonized Egg shell is 6.42% Elongate.
The yield stress values after the addition of CEPs to the Mg-Al2O3, Egg shell matrix. This the Mg-Al2O3, un carbonized Egg
shell is 87.27MPa yield stress and Mg-Al2O3, carbonized Egg shell is 73.56 MPa yield stress.
