Automated Inspection System

Under the Hi-rate Composites for Aircraft Manufacturing (HiCAM) Project, the National Aeronautics and Space Administration (NASA) /Langley Research Center (LaRC) is hereby soliciting information from potential commercial sources for an automated inspection system (AIS) capable of ply-by-ply inspection of carbon fiber reinforced polymer (CFRP) during the automated fiber placement (AFP) aerospace composite manufacturing process.

AFP has traditionally been used for building large acreage structures like wing skins, spars, and fuselages. Through the years, the AFP equipment has improved significantly in terms of meeting high material placement rates, but inspection processes have lagged behind. Some of it is due to the lack of advanced technology in this area while some of it is due to AFP users having different inspection requirements that equipment suppliers have to meet.

As a result, significant time is spent on manual/visual inspection of very large parts that significantly slows down the overall rate of the composites aircraft primary structure manufacturing process. In addition, the lack of recorded data limits understanding and improving for the process.

The primary goal of the HiCAM project is to demonstrate manufacturing approaches and associated technologies for large composite airframe structures that enable high-rate production (up to 80 aircraft per month) with reduced cost and no weight penalty versus 2020 technologies. The Project will develop and mature affordable high-rate composite manufacturing and assembly technologies, with reduced equipment and tooling costs, enabling a faster, more cost-effective production cycle for lightweight airframe structures.

In this regard, NASA has partnered with the United States Aircraft manufacturing industry to define and standardize the inspection requirements for AFP with the goal of identifying a commercially available, or commercially developed, AIS system capable of meeting the standardized inspection requirements. These standardized inspection requirements are defined in the RFI attachments.
