Composite on carbon fibre parts are by definition inhomogeneous. Fibre orientations in the part vary depending on the design. Lightweight parts in the automotive or aerospace industry are often quite complex, 3-dimensional structures.
Inspection of such parts has to deal with the reflection properties of carbon fibre. Profactor is developing sensor systems that use illumination from different directions and the analysis of image sequences to acquire accurate fibre orientation measurements in 3D. This is done by including reflection models of the carbon fibre in the image processing.
LScan – inline control for tow-placement processes
LScan is used for process monitoring of tow-placement processes. Typical defects such as gaps, overlaps, twisted tows or fuzzballs can be detected in real-time. The sensor system is mounted directly on the fibre placement head, so that corrections can be done immediately.
FScan – measurement of fibre angles on composite parts
FScan is a sensor technology that allows the accurate measurement of fibre angles on composite parts. The technology can be used for different types of materials (carbon, glass) and also during different stages of the production process (raw material, pre-form, clear-coated part). Aside from measuring the orientation it allows the detection of typical defects such as inclusions or distorted fabric.
HScan – Inspection of drill holes in composite components
HScan is a sensor system for testing holes in carbon fiber components or carbon fiber-metal composites. The inspection is carried out, for example, for bores for riveted joints and aims to detect process-related changes (tool wear) in good time on the basis of the quality of the inside of the bore.
DScan – Inspection of high-gloss surfaces
DScan is a sensor technology for the characterization of composite components with high-gloss surfaces, such as those used for high-quality interior components. The sensor characterizes the topography of the surfaces and calculates features that are more in line with the visual impression of the surface than is the case with conventional methods (profilometers).
