Computed tomography shows material density distribution and particle structures
Materials and components can be tested nondestructively using computed tomography (CT): The surface and the internal topology of the complete sample is mapped with a resolution down to the micrometer scale and imaged in three dimensions. A CT evaluation can comprise several qualitative and quantitative analyses, e. g. the particle structure, the density distribution and the dimensions. For example particle boards, MDF, OSB, WPC, plywood, insulation materials and wood foams can be measured. Samples with a size sufficient to evaluate local variations of the material quality (A4 and bigger) can be scanned with the equipment at Fraunhofer WKI.
