The Laboratory of Materials Analysis at CEITEC BUT conducts failure analyses of a wide range of metallic and non-metallic materials, including rubber, adhesives and sealants, paints/coatings and composites failure analysis.
Non-metallic material failure analysis offers a unique challenge because while the primary failure analysis sequence remains the same, the fractographic interpretation and analytical testing are very different from that used on metallic materials.
Due to the many material formulations and combinations, CEITEC's non-metallic material failure analysis laboratories often employ intensive material identification programs to assist in determining the origin of failure.
How does non-metallic and metallic materials testing differ?
Unlike metals, a non-metallic material typically cannot be identified from any single technique.
Often, chemical analyses are combined with thermal properties testing to form a clear picture of the material’s identity and origin. Non-metallic materials are evaluated for their structural properties, and any defects within that structure and the root cause of failure (macro microstructure, inclusion content, grain size, DAS, porosity, analysis of graphitic particles, etc.) according to valid standards.
