Process simulation helps authors problem research, survey the feasibility of replacing traditional steel materials in the automotive manufacturing industry in Vietnam by carbon fiber composite materials. In addition, the simulation also allows the author to easily change the contact angle, the velocity of impact on a flexible, easy to achieve high economic efficiency during the actual test.

INTRODUCTION Reduced self-weight of cars and increased passive safety are two important factors when designing automobile frames, shell. During the design process, typically some parts anticollision on cars will be made from synthetic resin to absorb energy. Also partial skeleton structure is also designed to be able to absorb the highest energy is intended to increase the reliability and safety of people and vehicles. The examination of the anti-collision or safety for people and vehicles are evaluated by analyzing the collision process. Impact assessment process is usually done under the following methods: - Experiment; - Simulation the impact of the software. The first selection method with the accuracy and reliability but high cost and implementation process is extremely complex, so not suitable for the current conditions in Vietnam. The application of simulation software collision between two cars to solve the problems of reliability frame, shell and passive safety has brought high accuracy while reducing costs and time of
