What Is ASTM D2344 Composite Short Beam Shear?
ASTM D2344 defines a standardized method for determining the short-beam strength of polymer matrix composite materials. The short-beam shear test uses a three-point bending configuration with a deliberately small span-to-depth ratio, which promotes interlaminar shear failure rather than flexural failure. The resulting short-beam strength is a practical measure of the laminate’s interlaminar shear capability and quality.
This test is widely used in composite manufacturing as a quality control tool to detect processing defects such as voids, delaminations, and improper cure, which manifest as reduced interlaminar shear strength. While short-beam strength is not a true material property for design purposes, it serves as an effective screening tool for composite laminate quality.

Our ASTM D2344 Testing Procedure
Specimen Preparation
Composite specimens are cut to the specified dimensions with controlled span-to-depth ratio.
1Span Setup
Three-point bending fixture is configured with the prescribed short span.
2Loading
Load is applied at a constant crosshead rate until specimen failure or large displacement.
3Strength Calculation
Short-beam strength is calculated from the peak load, span, and specimen cross-section.

ASTM D2344 Composite Short Beam Shear FAQs
It measures the short-beam strength / interlaminar shear strength (ILSS) of polymer matrix composites.
It is applicable to fibre-reinforced polymer matrix composites and laminates, including carbon fibre, glass fibre, and hybrid composites.
A three-point bending test is performed using a short beam specimen with a span-to-thickness ratio of 4:1.
It helps assess interlaminar bonding quality, resin performance, and delamination resistance.
Results are typically reported in MPa (Megapascal).
Interlaminar shear strength testing measures a composite material’s resistance to shear failure between its layers. A specimen is loaded in a testing machine, commonly using a short-beam configuration, until failure occurs. The maximum load is used to calculate apparent interlaminar shear strength, typically reported in MPa. ASTM D2344/D2344M is commonly used for short-beam testing of polymer-matrix composites.
An interlaminar shear strength (ILSS) test evaluates the bonding and shear resistance between layers of a laminated composite. The specimen is placed on two supports and loaded at the center until failure. The recorded load is used to calculate apparent interlaminar shear strength and assess composite quality.
