Abstract
This paper demonstrates the feasibility of manufacturing a light and low cost near-net-shape vertebra from Tailored Fiber Placement (TFP) preforms. The TFP preforms were produced flat and sewn together at the ends by a classic sewing process. Low pressure Vacuum Assisted Resin Transfer Molding (VARTM) was used for the consolidation and impregnation of the preforms. The molding strategy was oriented towards the use of silicone conformers to ensure a compaction that well fits the preform despite its imperfections. The resulting part required a light finishing. The mass was reduced by 40% and the manufacturing cost by 76% compared to the original part.
