Standard Test Method for Tensile Properties of Polymer Matrix Composite Materials
Theory:
Polymer Matrix Composites are used in many high-strength lightweight applications such as aerospace. Composites are finding their way into cars as well, especially to replace certain metal components.
Solution:
Wedge grips are the standard for testing polymers such as carbon fiber. While the material strength is high, so is the flexibility. Therefore, composite materials will tighten within the wedge jaws to create the perfect grip. Scientists must be sure to select the correct grip face especially if the material is somewhat slippery. Wedge grip jaws with different serration patterns are available.
