About this file
This file is a Request for Information (RFI) Features Table for NASA's High-rate Composites for Aircraft Manufacturing (HiCAM) Project, focusing on an Automated Inspection System (AIS) for carbon fiber reinforced polymer (CFRP) manufacturing. The detailed spreadsheet provides an extensive matrix of potential inspection features for automated fiber placement (AFP) processes, covering 32 distinct attributes ranging from tow gaps and overlaps to surface and buried defects like fuzzballs, foreign object debris (FOD), and tow-related anomalies. The features are categorized by detection probability (100%, 90%, and 70%), measurement type (continuous or attribute), and specific characteristics to be measured such as width, length, presence/absence, and dimensional variations.
The associated federal contract opportunity (Solicitation Number: 80LARC25RFI_AFP_AIS_2) reveals NASA Langley Research Center's objective to develop an inspection system that can support high-rate aircraft production (up to 80 aircraft per month) by addressing current limitations in automated composite manufacturing inspection. The project aims to standardize inspection requirements, reduce manual inspection time, improve data recording, and ultimately enable more cost-effective and efficient composite airframe structure production. NASA is seeking commercially available or developable AIS systems that can meet these standardized inspection requirements, with a focus on improving technological capabilities in the aerospace manufacturing sector.
