GB/T 41049-2021 specifies the test method for the bending properties of fiber metal laminates, applicable for determining the three-point bending strength, bending modulus of elasticity, bending stress, and load-deflection curve of such materials. The standard defines the test principle, specimen preparation, conditioning, and operational procedures. It primarily utilizes a universal testing machine (with an accuracy class of 1.0 or higher), paired with instruments such as calipers (with an accuracy of no less than 0.01 mm), deflection gauges, or strain gauges. The test employs a three-point bending loading mode, applying a constant rate of load until specimen failure. During the test, load and deformation data are recorded simultaneously, and key performance indicators are calculated through processing. This provides a unified technical basis for material application design and quality control.
