Testing Products for ASTM D7264
APP-D7264Flexural Properties of Polymer Matrix Composites. Determines flexural stiffness and strength using 3 or 4-point loading.
Application Insight:
Replaces D790 for high-modulus composite materials.
Pro Tip:
Use a span-to-thickness ratio of 32:1 to minimize shear.
