ASTM D2344: Standard Test Method for Short-Beam Strength of Polymer Matrix Composite Materials and Their Laminates
This test is used for determining the interlaminar shear strength of parallel fibers. Applicable for reinforced plastics and composites, the data is used for purposes concerned with interplay strength and comparing composite materials.
After conditioning and machining to appropriate specifications, the specimen is placed on a horizontal shear test fixture such that the longitudinal axis is perpendicular to the loading beam.Â The support span is set to reflect a ratio of the thickness of the specimen.Â The nose applies load to the specimen until breakage.
