The effect of adding waste of cement "fly ash" in some of the mechanical properties of NBR composites

الملخص EN

Composite materials consist of merging two materials or more are different in mechanical and physical properties, The aim of research is to study the effect of changing in the rainforcment percentage by fly ash in mechanical Properties ,for composite material consist of NBR rubber rainforced by carbon black (40pphr)and fly ash (0,15,18,20,23,26,30 pphr), which included tensile strength, modulus, elongation, hardness, tear, rasillince, after rainforced NBR rubber with different weight percentage from fly ash and study the effect on above Properties as illustrated in the diagrams.
