This system establishes the short-beam strength of reinforced composite materials with high modulus. The specimen is a short beam machined from a curve or a plate rolled up to 6,00 mm [0.25 in.] thick. The beam is loaded in three-point bending. Application of this test method is limited to continuous- or discontinuous-fiber-reinforced polymer matrix composites, for which the elastic properties are balanced and symmetric with respect to the longitudinal axis of the beam.
