The present work aims to describe the behavior of the interface using the method of load transfer between fiber and matrix in a composite material. Our contribution was first to simulate the mechanical behavior of a composite, for a given radius of the fiber was able to automate the result for different rays thus different proportions of the reinforcement, the simulation was done with software as covered COMSOL Multiphysics with MATLAB, taking into account the boundary conditions. The thermomechanical behavior is deduced by a mathematical model that describes the variation of the shear stress along the interface; It is found that the shearing of the interface increases with the crosslinking temperature. This increase is partly due to the difference in expansion coefficient between fiber and matrix.
