The natural bers are indeed a renewable resource, biodegradable and naturally with technical qualities and very high mechanical properties. The mechanical properties of reinforcement biocomposites as alfa / polylactic acid (PLA) are largely conditioned by the interfacial bond between the two materials (ber and matrix). To characterize this link and locate damage to the ber-matrix interface, we used a genetic approach based on the Cox model and formalism of Weibull. This model taking into account the micromechanical behavior of the three composite and biocomposites materials: Glass/epoxy, alfa / epoxy and alfa / PLA. The results of this simulation show that the damage level of the interface is related to the nature of the materials used and the applied mechanical stress, and has shown that the green material alfa / PLA is stronger than the biomaterial alfa / epoxy. The results of this modeling are in agreement with those obtained experimentally by Antoine et al. So the natural bers have a very important role in enhancing the mechanical strength of composite and biocomposites materials.
