| Abstract | ||
| In this work , the adding of silicon carbide particles as well as cadmium oxide or the mixture to poly sulfon amides to form a composite material is studied . The influence of adding different particles weight (in percent) on the material mechanical properties is investigated by performing several experiments to test the hardness , compression strength , impact strength and bending strength . The results have show that the values of hardness are higher when the particles of silicon carbide are added to poly sulfon amides in comparison with the addition of cadmium oxide or the mixture adding of (silicon carbide + cadmium oxide) . The results reaches the highest values when 8% is added as a particles weight of [(285 , 270 and 255 ) Shore D] respectively . While the results for compression strength are of (180 MPa , 175 MPa and 170 MPa) respectively for silicon carbide, cadmium oxide and the mixture of (silicon carbide + cadmium oxide) . In terms of the impact strength, higher strength is observed when the silicon carbide is added to poly sulfon Amide from cadmium oxide or the mixture of (silicon carbide +cadmium oxide) particles and up to 2% of the weight in the correct order (99 KJ/m² , 95 KJ/m² , 90 KJ/m² ) respectively . Also , the bending strength is higher when the mixture of (carbide silicon + cadmium oxide) particles is added to poly sulfon Amide from carbide silicon and cadmium oxide mixture and would reach the highest when 2% is added as a particles weight in the following order (400MPa , 350MPa and 335MPa) respectively. From the results obtained , both carbide silicon and cadmium oxide, have ability to improve the mechanical properties of poly Sulfon Amide such as hardness , comparison strength , impact strength and bending strength , this mechanical properties which is the highly demanded property in the polymer applications. | ||
