Development of new recycled rubber/aluminum powder composites is gaining traction due to their potential to combine the environmental benefits of recpmpmycled rubber with the enhanced properties provided by aluminum. These composites offer a sustainable and high-performance alternative for various applications. The incorporation of recycled rubber and aluminum powder into polymer matrices not only enhances sustainability but also fosters the development of durable, environmentally friendly, and high-performance composite materials. These materials hold promise for applications in construction and beyond, offering versatile solutions to various engineering challenges. In this context, the present study delves into the hyperelastic behavior of this advanced composite made of Recycled rubber matrix reinforced with different volume fractions of aluminum powder. An optimization algorithm is used to identify the hyperelastic parameters of recycled rubber/ aluminum powder composite for different volume fractions of aluminum content. Then, the focus of this study lies in its application to three-point bending process, to analyze the influence of aluminum powder reinforcement on von Mises stress distribution.
