ASTM Committee D-30 on High Modulus Fibers and Their Composites proposed a new standard to measure in-plane shear properties of high modulus fiber composites. The new method would use a two-rail or three-rail shear test system, both of which are being used in industry at this time. During the Subcommittee D-30.04 review, several suggested modifications were offered which indicated a lack of uniformity between the methods in current use. Another problem was that one laboratory had tested material with both methods and obtained different values with the two-rail versus the three-rail shear test systems. It was decided to run a round-robin using both test systems.
