مختصر البحثThe rubber materials is very important materials its using in large engineering application, therefore, the modified for mechanical properties and behavior for its materials investigation form many researchers. But, more researchers were focused on the investigation for properties of its materials by variable the amount for each compound adding in composition of the rubber material. But, this processing given modifying for properties and behavior did not exceed about (20%). Therefore, from previous my paper presented for modified materials by reinforcement with Nano particle materials shown that the mechanical properties and behavior increasing with high value lead to about (60%), as in composite materials. Then, in this paper, investigation the modified for mechanical properties and creep behavior for rubber materials by reinforcement with carbon multi wall Nano particle materials. Where, the investigation include evaluated the mechanical properties (strength for rubber) and mechanical creep behavior with various weight fraction effect for Nano particle materials. There, the study was achieved through experimental technique by manufacturing multi rubber samples with different Nano particle weight fraction, and then, test its samples by tensile and creep machines to evaluate mechanical properties and behavior for its materials. There, the weight fraction for Nano particle used are (0,0.2,0.4,0.6,0.8,and 1% wt). In addition, the creep behavior investigation numerically by using finite element technique with using Ansys package, and then, comparison the results evaluated together with experimental calculated results. Where, the comparison shown that the maximum error not exceed (8.36%). Finally, the investigation shown that the mechanical properties and creep behavior for rubber materials modified to about (65%) with reinforcement by (1%wt) for multi wall carbon Nano material
