Study and modeling of thermomechanical properties of jute and Alfa fiber-reinforced polymer matrix hybrid biocomposite materials

In this paper, we have investigated and studied the effect of thermal stress on the fiber-matrix interface damage of three new hybrid biocomposite and biocomposite materials. Our genetic simulation based on Weibull probabilistic models showed that the jute-Alfa/PEEK (PEEK: thermoplastic matrix-polyetheretherketone) hybrid biocomposite material is more resistant to the mechanical and thermal stress applied comparing with the other biocomposites such as jute/PEEK and Alfa/PEEK with the same volume fraction used in our genetic model. Our results also show that natural fibers improve the physical properties of biocomposite materials, especially hybrid biocomposite materials. This finding is similar to that found by Antoine Le Duigou et al. where they have shown experimentally that the natural reinforcements greatly improve the properties of composite materials and also they have a very low environmental impact.
