Objective: In our previous work, we have developed and characterized a composite material based on cassava starch reinforced with coconut fibers. We will modelyse and simulate its thermo-mechanical behavior. Methodology: For this, we start from Hooke's law to establish a behavior model to evaluate the Young's modulus of each phase (matrix and fibers) as a function of temperature. This is then used in different homogenization models (Voigt and Mori-Tanaka) to approximate the thermoelastic behavior of the composite. Finding: It is noted that the mechanical behavior of the material deteriorates when the temperature increases. Applications: The type of behavior obtained is compared with other previous general results on materials. The biodegradable composite obtained can be used in the field of plastics in the concept of sustainable development.
