On an Original Approach to Model Hemp Fibers Reinforced Thermoplastics
This paper is devoted to present an approach to model behavior of hemp fibers reinforced thermoplastic composites. Experimental investigations using common testing methods have shown that major physical dissipative phenomena which explained the behavior of polypropylene/ hemp fibers (PP/Hemp) composites took place in the matrix. Moreover these dissipative mechanisms are mainly due to matrix cracking. The behavior modeling of PP/hemp fiber composites is obtained by a two-step modeling strategy. A real based microstructure is automatic generated by own made algorithms according to the observed microstructure by X-ray tomography and constitutive behavior of the matrix is obtained using the micromechanics formalism and is implemented by a FORTRAN routine in ABAQUS® software. This approach seems to have the potential to describe behavior of such composites (PP/Hemp).
