3 Terms and Definitions

The following terms and definitions defined in GB/T 3961 apply to this document. 3.1 Bending percentage percentbending The bending deformation of the sample is characterized by the difference in the indication value of a pair of longitudinal strain gauges pasted back to back at the center of the front and rear surfaces of the sample during the test. degree of shape.

4 principles

A multi-directional laminate sample without a center hole is used, and the sample/fixture assembly is clamped in the chuck of the testing machine for loading, so that the working section of the sample is uniform. Evenly loaded, the compressive properties of multi-directional laminates are obtained.

5 Test equipment
