Finite Element Modeling of a Semi-Cylinder Polymeric Composite Product Under Impact and Thermal Conditions

摘要

Composite products have now reached very important production volumes in many avant-garde industries or always innovative industries such as automotive or aerospace.Composite products allow engineers to adjust the formulation to meet specific strength or temperature requirements of any application.In short by combining specific materials and adjusting them,polymeric composite products can be tailored to any vehicle.Polymer composite products for car bodies have component areas in the form of semi-cylindrical surfaces.The good behavior of these types of surfaces on impact or high temperatures is a requirement of traffic safety conditions for participants.Paper presents the results of research on modeling and impact simulation of these types of products besides a transient temperature analyze using the finite element method.Thus,the state of stress and deformations resulting from a structural analysis are highlighted,as well as the variation of temperatures from the transient thermal analysis.This results in suggestive researches images from which conclusions can be drawn regarding the possibility of using such polymeric composite structures in the automotive industry.As a result of the research carried out,in solutions for optimizing the body profile,the constructive typology of the polymer composite product and the manufacturing technology,respectively,leading to the increase of the safety of the traffic participants in optimal vehicle manufacturing conditions.
