Case Study: ST Engineering achieves 80% less CFRP waste and 96% first-time-right yield with SAP S/4HANA

Middle River Aerostructure Systems Bringing Blue-Sky Thinking to Aviation Innovation

ST Engineering’s Middle River Aerostructure Systems (MRAS) needed to modernize factory operations to support sustainability goals, reduce waste, and improve first-time-right quality for time-sensitive aerospace composite parts. Using SAP S/4HANA and related cloud capabilities, the company wanted better visibility into materials, tooling, and production planning while cutting cycle times and improving efficiency.

SAP, together with Plataine solutions, helped MRAS create a single source of truth across inventory, batches, shelf life, and production data, enabling real-time scheduling and material decisions. The result was an 80% reduction in CFRP material waste, a 96% first-time-right yield for composite nacelle structures, a 5% increase in operational efficiency, and a drop in kitting and layup cycle times from four hours to 12 minutes.
