ASTM D2344/D2344M Short-Beam Strength (Short-Beam Shear) Test for Polymer Matrix Composites

← Back to all standards

ASTM D2344 is the test method for the short-beam strength of polymer matrix composites and their laminates. To match this to your program, talk with our team.

What ASTM D2344 Covers

It gives a quick apparent interlaminar shear strength by loading a short, thick beam in three-point bending so that shear between the plies dominates failure.

How the Test Is Run

A short-span specimen is loaded in three-point bending at a controlled rate until it fails, and the short-beam strength is calculated from the peak load and cross-section.

Why It Matters

Short-beam strength is a fast screening indicator of interlaminar quality and cure; a rigid short-span fixture is required.
