Finite Element Simulation of Mechanical Properties and Crack Propagation Damage of Carbon Fiber and Carbon Black Reinforced Rubber Composite Materials
In order to study the mechanical properties and crack propagation mechanism of carbon fiber/rubber composites and carbon black/rubber composites,the effects of different volume fractions of fillers on the mechanical properties of composites were firstly analyzed.Then,the crack propagation damage evolution of carbon fiber/rubber composites and carbon black/rubber composites was studied based on the extended finite element method.The effects of reinforcement volume fraction on the tearing energy and J integral of rubber material in the process of crack propagation under uniaxial load were explored,and the crack propagation damage law of carbon fiber and carbon black reinforced rubber matrix composites was analyzed.The results show that the effective elastic modulus of rubber composites increases with the increase of reinforcement volume fraction.
