TENSILE GRIPS Instron® offers both manual and hydraulic grip types capable of operating over a wide range of temperatures. Moving body manual and hydraulic wedge grips are recommended for testing composite materials as they provide reliable gripping of test specimens while maintaining accurate and repeatable alignment that meets Nadcap requirements for aerospace testing. When it is necessary to change the test setup, we offer adapters that allow composites test fixtures to be attached to these grips. This minimizes disruption and increases productivity, as labs do not need to remove high...

COMPOSITE FIXTURES Solutions for Composites Testing Supported Gauge Section Compression Test Fixture ASTM D695, ASTM D3846, Boeing BSS 7260, SACMA SRM-1, prEN 2850, ISO 14126 The anti-buckling fixture was originally designed for the compression testing of rigid plastics per ASTM D695 and the shear testing of reinforced plastics per ASTM D3846. Boeing then adapted the fixture for use with high strength composites, introducing an L-shaped base support to ensure accurate and consistent alignment of the fixture and specimen. The SACMA standard followed the Boeing design with an added...

SCAN THE QR CODE to learn more about our composite fixture offerings Compression After Impact - “Boeing CAI” Fixture Compression After Impact - Airbus AITM 1-0010 The “Boeing CAI” fixture is used to test the impact resistance of carbon and other fiber-reinforced polymer composite laminates. These materials are prone to great reduction in compressive strength, even when the impact load is insufficient to cause visible damage. The post-impact compression test is used to assess the relative performance of different composite laminates with different fiber matrix combinations. Laminates are...

COMPOSITE FIXTURES Solutions for Composites Testing Flatwise Tension Test Fixtures Boeing Open Hole Compression Fixture ASTM D6484, ASTM D6484M, Boeing BSS 7260 This fixture is designed for ASTM C297 testing to determine the bond strength between the facing and core of a sandwich core panel, or the strength of the core itself. The specimen is bonded to thick loading blocks and then subjected to tensile loading applied via the blocks. The fixture can be used to test a variety of different sandwich core materials including honeycomb core structures and continuous core structures such as foam...

V-Notch Shear Test Fixtures Composites Rail Shear Flexural and Interlaminar Shear Bend Instron® shear test fixtures are designed for in-plane or interlaminar shear testing of composite materials. The V-Notched Rail Shear Method was introduced in 2005 under ASTM D7078 and includes the distinctive V-notches in the specimen design, which serve to create a localized and approximate uniform shear stress zone between the notches. This fixture is used to determine the in-plane shear strength of a composite laminate panel in accordance with ASTM D4255. ASTM D4255 describes both 2 rail and 3 rail...

STRAIN AND ENVIRONMENTAL SOLUTIONS Solutions for Composites Testing Averaging Axial & Biaxial Extensometers Automatic Contacting Extensometer Average axial strain is determined from independent strain measurements on opposite sides of the specimen. The use of average strain eliminates errors due to specimen bending and allows the determination of precise modulus values. By integrating a transverse strain transducer, this extensometer can simultaneously measure average axial and transverse strain. Bonded Strain Gauge Adapters Bonded strain gauges are attached to the surface of a specimen...
