충격보강제가 포함된 나일론6에서 Izod 충격시험의 컴퓨터 모사

Impact modifier reinforced polymers are frequently used. In this study, Izod impact test has beensimulated to analyze the mechanism of impact reinforcement of Nylon6 which contains impact modifier. Themodeling of rubber particles added to Nylon6 as an impact modifier has been attempted. Based on the modeling,simulation of Izod impact test has been performed to observe the distribution and direction of stress at thecross-section of impact specimen. Three computer simulation models for Nylon6 were investigated. Those werewithout impact modifier, containing impact modifier without surface treatment, and containing impact modifierwith surface treatment in the Nylon6. Simulation results showed that the stress which originated at the notchsurface propergated to the inside of specimen round a impact modifier. In addition to that, impact modifierreinforced Nylon6 specimen showed low stress ditribution in the cross-section specially at notch surface. Principalstress in perpendicular direction to crack was also lowered in impact modifier reinforced Nylon6. These enhancedimpact resistance reduced and crack propergations. Through this study it was realized that the computer simulationcan be utilized to investigate the property enhacement of composite materials.
