New Sensor for Detecting Defects in Lightweight Structures

"Defect Defender," a sensor developed by the Laboratory for Machine Tools and Production Engineering at RWTH Aachen (WZL), measures the geometry and fiber orientation of carbon-fiber reinforced plastic surfaces in 3D.
  - Light and strong at the same time - this is what designers want from a material that can be used to manufacture energy-efficient components. Lightweight components made of carbon-fiber reinforced plastic possess these characteristics. They consist of two components: high-quality carbon fibers and a plastic matrix into which these fibers are embedded. This composite provides a unique potential for lightweight construction for numerous applications, such as in the aeronautics and space industry or automotive manufacturing. While carbon-fiber reinforced plastics are becoming increasingly important, the level of automation in the manufacturing processes is still very low, and material costs are high. Currently, most components made of composites are manufactured manually or using partially automated processes. This requires both a lot of time as well as being expensive.
