Composite Manufacturing Challenges in Aerospace & Defense
Track: NX CAM and Tecnomatix User Connection
As the demand for fuel efficient airplanes grows, the usage of composite materials in the airframe and aero-engine industries grows. We can see a growing trend in the usage of composite materials, from around 5% (by weigh) of the airframe during the 80’s to around 50% in Boeing 787 and Airbus 350. Composites parts manufacturing is very complex as the mean rework/scrap rate for these parts in the A&D industry is ~4.5%. This is a very painful point for the air framers as, not only these materials are very expensive, this high rate of scrap/rework poses a risk of delivering the parts late and affect the cash flow and reputation of the air framer. In my session, I will show an overview of the challenges for manufacturing composites parts and I will also show how Siemens PLM and our partner Plataine can offer a joint solution to mitigate the challenges of composites manufacturing from the part design phase, through the manufacturing planning to the shop floor, offering a digital thread to manage the composites manufacturing and to track the materials, parts and assets at the shop floor to avoid expiration of raw composites materials, thus, avoid usage of expired materials and performing the manufacturing as designed in order to eventually increase the quality and reduce the amount of scrap/rework.
