ASTM D7264 testing determines the flexural stiffness and strength properties of polymer matrix composites. Data from this test method will result in strength, stiffness, and load deflection/behavior of the polymer matrix composite material under test.

Testing may be performed using a four-point or three-point loading fixture. The difference between three-point and a four-point bending methods is the location of the maximum bending moment and the maximum bending stress. In three-point bending, the maximum axial stress fiber will be located directly under the loading point. In four-point bending, the bending moment and maximum flexural stress is constant between the central force application members. In three-point bending, there is a resultant shear force everywhere in the beam except directly under the mid-point force application member. In four-point bending, the area between the central force application members has no resultant shear force.

The flexural properties determined by this method can be used for quality control, specification purposes, and design applications.
