The Challenges of Testing Composites and the solutions to overcome them

Full characterization of the properties of anisotropic and inhomogeneous composite materials requires a wide range of mechanical tests including tension, compression and shear tests. In qualification and materials development, other test types are used to explore more complex properties, such as open hole tension/compression (OHT/OFC), inter-laminar fracture toughness, compression after impact (CAI), and fatigue. Tests need to be conducted over a range of temperatures on materials that may have been conditioned in a variety of environmental conditions such as high humidity and immersion in fluids.

Common challenges of testing composites include repeatability, alignment, and strain measurement. Instron offers extensive testing knowledge and a comprehensive range of solutions for testing materials and components – including testing systems, fixtures, accessories, and software.
