    Abstract

    A new Iosipescu shear test fixture design that can be used to perform the test procedure outlined in Test Method for Shear Properties of Composite Materials by the V-Notched Beam Method (ASTM D 5379) was designed, fabricated, and tested. The new fixture solves the often reported problems of specimen twisting, variability of results, and differences in measured shear modulus between [0]16, [0/90]4s, and [90]16 laminates. Lateral instability of the Iosipescu specimen is explored as the main agent causing the undesirable effects observed with the previous fixture design.
