GB/T 31541-2015 provides for the determination of tensile and shear bond strength at the interface of fine ceramics by the cross-sectional method. The standard specifies the required equipment, such as material testing machines with precise loading capabilities. Detail the preparation of cross-shaped fine ceramic specimens, place them on the equipment, and apply tensile and shear forces according to the specified loading rate. Interfacial tensile and shear bond strength are calculated by measuring the load on the specimen when it breaks. This standard provides a normative method for evaluating the interfacial bond performance of fine ceramic materials, helping to ensure their structural Reliability in related engineering applications.
