 In this study, a new approach to recycle defective ceramics was explored by incorporating them into composites for use in the automotive industry. The resulting centered clay microparticles were mixed with an unsaturated polyester resin matrix and then cast into molds. The bending test results demonstrated an elastic linear behavior which is typical of a fragile material. Scanning electron microscopy revealed a good dispersion of the microparticles and a fragile failure mechanism. A finite element analysis was conducted to optimize the design of a motorcycle brake lever, demonstrating improved stress distribution and reduced mass compared to the original part. Finally, a prototype brake lever was manufactured using the optimized geometry. This study shows that defective ceramics can be successfully reused in composites for automotive applications.
