Abstract | ||
This research tries to study the using of rice husk (RH) as a filler with rubber compound based on Natural rubber (NR) that was prepared using an mixing mill about 80 ̊C and 50 rpm with different weight fraction (part per hundred Rubber) as (0-5-15-25pphr)with particle size between (250-500) µm , the results show the tensile strength and viscosity decreased with RH loadings in the matrix, while the tensile modulus and hardness showed an opposite trend. The weak filler -matrix interaction, resulting in poor filler dispersion and large agglomerated particles size, caused those properties to decrease. However, some mechanical properties of the rubber compound can be slightly improved with the addition of (RH) into the matrix while other properties decrease weather the overall rheology properties for all samples almost being little change | ||
