Book excerpt: This work aims at the production and characterization of hybrid composites based on a thermoplastic polymer (high density polyethylene, HDPE), a natural fiber (hemp) as reinforcement and ground tire rubber (GTR) as an impact modifier. The addition of a coupling agent (maleated polyethylene) is also investigated. The samples are compounded by twin-screw extrusion and produced by injection molding. From the samples obtained, a complete morphological and mechanical characterization is performed. The results show that good dispersion is obtained due to the selected processing conditions and good interfacial adhesion between all the phases is achieved due to the presence of maleic anhydride grafted polyethylene (MAPE). Finally, for selected mechanical properties, nonlinear regression models are proposed to predict and control the final properties of these compounds and comparisons are made based on the neat matrix properties.
