The increasing public demand in the world automotive industry to improve the environmental sustainability of their manufactured vehicles without sacrificing drivers' comfort and safety and the high cost of lightweight materials have driven researchers to reconsider materials used in the automotive application. Thus, this work aims toward the production of environmentally sustainable, high-performance, lightweight composites, utilizing recycled carbon fibers (RCFs) and pyrolyzed tire particles (PTPs) reclaimed from pyro-gasification of CFRP wastes and end-of-life tires (ELTs), respectively, as reinforcements for cardanol-based epoxy resins. The fabricated composites exhibited rubbery-like behavior at 25 °C. Spectroscopic, rheological, physical, thermal, thermomechanical, and mechanical characterizations were performed to fundamentally understand the processing-structure-property relationships of the manufactured composites. In addition, laminates interleave with cardanol-based epoxy resin, and RCF-reinforced cardanol-based epoxy composites widen the energy dissipation to lower temperatures, implying better fracture toughness. For the hybrid composite, the interlocking effect of combining RCFs and PTPs resulted in higher Tg and better thermal stability compared to the composites with a single type of reinforcements. These material behaviors demonstrate that these composites represent interesting candidates for producing sustainable, lightweight, and low-cost anti-vibration components.
