تاثير اضافة حشوات اسود الكاربون والكرافيت على الخصائص الميكانيكية للبولي بروبلين

Abstract

The important increasing for using polymeric composites came from results of industrial and large to chnology development which it was seeing in world and substitute from traditional engineering materials which its used in industry . so the present research aim to preparation of new polymeric composites with good mechanical . So we preparing the polymeric composites from polypropylene with black carbon and grafphite with different percentage (1%,2.5%,5%,7.5%,10%,12.5%) . The results had show of mechanical properties increase of value the Young Moululs and tensile strength and tensile strength at break and decrase impact strength and % Elongation at break ,the value at of Young Moululs( 3020 , 3200 MPa) for carbon black and graphite respectively at the (12.5%) perceatage. were best ratios to increase of the tensile strength to black carbon the value of tensile(41.3 MPa) and graphite (7.5%) the value of tensile (43.4 MPa) .for tensile strength at break (28.6, 29 MPa) for carbon black and graphite respectively at the (12.5%) perceatage.
