The manufacturing of carbon fiber-reinforced polymers (CFRPs) components is penalized by high production time and cost of robust molds, typically obtained by machining of metal blocks, to support many autoclave cure cycles. However, they are cost-effective when many parts are produced. For small batches or customized parts production, 3D printing can provide significant cost and time savings alternative in mold realization. In this framework, a CFRP mold for manufacturing sports car's components were realized by a 3D printer based on the Fused Filament Fabrication technology. The mold was subjected to a thermal cycle to investigate its behavior after a typical curing autoclave process. Mold dimensions were acquired by means of pre- and post-processing measurements to evaluate the deformations.

Abstract
The manufacturing of carbon fiber-reinforced polymers (CFRPs) components is penalized by high production time and cost of robust molds, typically obtained by machining of metal blocks, to support many autoclave cure cycles. However, they are cost-effective when many parts are produced. For small batches or customized parts production, 3D printing can provide significant cost and time savings alternative in mold realization. In this framework, a CFRP mold for manufacturing sports car's components were realized by a 3D printer based on the Fused Filament Fabrication technology. The mold was subjected to a thermal cycle to investigate its behavior after a typical curing autoclave process. Mold dimensions were acquired by means of pre- and post-processing measurements to evaluate the deformations.| File | Dimensione | Formato | |
