Delamination Testing

Delaminations and laminar defects can significantly compromise the strength, structural integrity and service life of components. Particularly in fiber-reinforced composites, multilayer materials and metallic semi-finished products, such discontinuities often remain invisible from the outside. FOERSTER provides non-destructive inspection solutions to detect hidden layer separations and internal discontinuities, helping manufacturers ensure consistent material quality and component reliability.

Delaminations can develop during manufacturing or as a result of mechanical and thermal stresses during service. They occur when individual material layers separate or exhibit insufficient bonding at their interfaces. In carbon fiber-reinforced plastics (CFRP), glass fiber-reinforced plastics (GFRP) and sandwich structures, such defects can significantly compromise structural integrity. In metallic semi-finished products such as plates, coils and tubes, similar discontinuities may occur in the form of laminations and internal separations. As these defects often remain hidden within the material, early detection is essential for ensuring the quality and reliability of inspected components.

FOERSTER offers non-destructive inspection solutions for a wide range of materials and component geometries. Depending on the material and inspection requirements, technologies such as active thermography and ultrasonic testing can be applied. Active thermography uses controlled thermal excitation to reveal changes in heat flow that may indicate hidden delaminations and interfacial defects. Ultrasonic testing detects internal discontinuities by analyzing the propagation and reflection of sound waves. Both technologies provide application-specific capabilities for identifying material defects without damaging the inspected component.

With extensive expertise in non-destructive testing, FOERSTER supports manufacturers and operators in the reliable detection of delaminations and laminar defects. Early identification of critical discontinuities enables targeted quality control, reduces the risk of defective components and contributes to safer manufacturing processes and improved long-term product reliability.
