Recycling Glass and Carbon Fibers for Reusable Components in the Automotive Sector through Additive Manufacturing

This work explores the use of additive manufacturing (AM) to reprocess recycled glass and carbon fibers in automotive sector. It aims foster exploitation Glass Fiber Reinforced Polymers (rGFRPs) Carbon (rCFRPs) through two workflows: indirect Fused Filament Fabrication (FFF) UV-assisted Direct Ink Writing (UV-DIW). An industrial case study on vehicle components has been considered by prototyping one real component. After tensile tests, some molds were fabricated with a FFF 3D printer for printing process cast an epoxy-based thermosetting resin rGFs rCFs. The second technology consisted fabricating parts hardening in-situ photo- thermal-curable acrylic liquid rGFs. These results validate AM composites applications approaches may be implemented customizable batches below 100 vehicles as first step their exploitation.
