This The aim of this work was to study the influence of Calcium Carbonate CaCO3 nano-particles (N-CC) in preparation NR compound . Four compositions of NR/ CaCO3 nanocomposites with filler loading Calcium Carbonate of [ 0, 3, 5, 7 and 10 ] hpr, the compositions were prepared in Laboratories Inc. Tires Babylon. To determine the crack growth fatigue at test device called (Me Mattia device) was used According to [ASTM D813], operating at a constant speed under load and giving 300 flexing cpm. The test included the Crack growth Fatigue properties of NR/ CaCO3 nanocomposites compound using a vulcanization system [ASTM D3182]. The Material of filler used in this research is Carbon black (N326 ) with quantity constant (50 pphr). The crack growth fatigue test shown that the crack length is decreased with the increasing of percentages of CaCO3 nanoparticles.
