Fabrication and Testing of Composite Materials From Rubber

Abstract

Recently, there has been considerable interest in forming Filler as a means to improve several properties of Elastomers. For this purpose layered (CaCO3 and Stiric Acid "S.A" )  are now widely being used. These layered  are a class of inorganic materials that are naturally layered in structure  , 8 different rubber compound were prepared by using (SBR 1502) type of Styrene Butadiene rubber in level and each recipe reinforced with carbonate calcium  (CaCO3 ) at constant  ratio (60) pphr ( part per hundred ), Stearic Acid (S.A) at variable ratio (1,2,3,4,5,6,7 and 8) pphr  The physical properties such as Tensile ,Elongation , Young Modulus and Compression were Studied . The result show that the hardness, Fatigue, Compression, wear, increase with loading level of (S.A). But the Tensile and Elongation that increase with excited ratio of (S.A) and decrease in another Value at 100 %.
