Effects of rCF attributes and FDM-3D printing parameters on the mechanical properties of rCFRP

In order to realize high-quality and environment-friendly recycling of carbon fiber reinforced composite (CFRP) waste and high-value reuse of recycled carbon fiber (rCF), this paper proposes an additive remanufacturing process of recycled carbon fiber reinforced composite (rCFRP). The material attribute of rCF recycled by the thermally activated oxide semiconductor was analyzed and the effect of fused deposition modeling-3D (FDM-3D) printing parameters on mechanical properties of rCFRP was investigated, and FDM-3D printed rCFRP products for automotive were prepared. The results illustrate that rCF possesses the same excellent material attribute as the virgin carbon fiber, and optimizing FDM-3D printing parameters can effectively improve the mechanical properties of rCFRP. FDM-3D printed rCFRP products are of promising application in the field of automotive lightweighting due to its characteristics of personalized customization and low cost, which verifies the feasibility of the additive remanufacturing process mentioned above.
