Polymer Shear loading Compression test Fixture

ASTM D3410

UnitedTest ASTM D3410 Polymer Shear loading Compression test Fixture used to determine in-plane compressive properties by applying the compressive force into the specimen at wedge grip interfaces. ASTM D3410 is most appropriate for composites materials reinforced by high-modulus fibers including tape and textile, but other materials may be tested. The test fixture is designed to provide a compressive load to the unsupported center 12 to 25 mm (0.5 to 1 inch) gauge length of the specimen.

General introduction

UnitedTest ASTM D3410 Polymer Shear loading Compression test Fixture used to determine in-plane compressive properties by applying the compressive force into the specimen at wedge grip interfaces. ASTM D3410 is most appropriate for composites materials reinforced by high-modulus fibers including tape and textile, but other materials may be tested. The test fixture is designed to provide a compressive load to the unsupported center 12 to 25 mm (0.5 to 1 inch) gauge length of the specimen. 

Compressive Properties of Polymer Matrix Composite Materials by Shear Loading ASTM D3410


Test Procedure:

A fixture is used to align the specimen in the wedge grips and the grips are therefore tightened. The wedges are inserted into the compression fixture, and if an extensometer is being used to measure strain, it is attached to the specimen. The specimen is compressed to failure.


Specimen size:

Specimens should have a uniform rectangular cross section, 140 mm to155 mm (5.5 in to 6 in) long. The recommended width can be 12 mm (0.5 in) or 25 mm (1 in). A variety of thicknesses can be accommodated. Tabs can be bonded to the ends of the thin specimens to ensure failure in the unsupported gauge length.


Compressive properties tested:

Ultimate compressive strength

Ultimate compressive strain

Compressive chord modulus of elasticity

Compressive Poisson’s Ratio

Three-part failure identification codes

ASTM D3433 Cleavage Fracture Test for Adhesive Bonded Metal Joints –

ASTM D3433 Standard Test Method for Fracture Strength in Cleavage of Adhesives in Bonded Metal Joints

ASTM D3433 determines the fracture strength in cleavage (Mode I opening) of adhesives when tested on standard specimens under specified preparation and testing conditions, delivering the critical strain‑energy‑release‑rate values GIc (initiation toughness) and GIa (crack‑arrest toughness). It focuses on linear elastic fracture mechanics (LEFM) characterization of crack propagation resistance in metal-adhesive joints, with optional adaptation for plastic adherends when rigidity/thickness corrections are applied. 

ASTM D3410 Shear Loading compression Test for Polymer Matrix Composite Materials with Unsupported Gage Section –

ASTM D3410 Shear Loading compression Test Method for Compressive Properties of Polymer Matrix Composite Materials with Unsupported Gage Section. 

ASTM D3410 measuring in‑plane compressive properties for high‑modulus‑fiber‑reinforced polymer‑matrix composites using pure shear‑loading via wedge grips, with an unsupported gage section on the test coupon. Test method determines the in-plane compressive properties of polymer matrix composite materials reinforced by high-modulus fibers. It is applicable to composites made from unidirectional tape, wet-tow placement, textile (for example, fabric), short fibers, or similar product forms. Some product forms may require deviations from the test method.

ISO 16525-4 Isotropic Electrically Conductive Adhesive Shear & Electrical Resistance Test –

ISO 16525-4 Adhesives — Test methods for isotropic electrically conductive adhesives — Part 4: Determination of shear strength and electrical resistance using rigid-to-rigid bonded assemblies

ISO 16525-4 defines how to build a millimetre-scale ("miniature") bonded joint out of two rigid metal adherends and an isotropic conductive adhesive (ICA), then break it in shear while continuously measuring the joint's electrical resistance, so that mechanical strength and electrical continuity are evaluated on the same specimen at the same time.  UnitedTest  Test Machine
