Validated measurement techniques for improved design of large advanced composite structures subjected to multi-axial loading

This project will develop the measurement infrastructure to support the increasing trend within a range of industrial sectors to fabricate components such as aircraft wing boxes, yacht masts and wind turbine blades from thick material sections.

Multi axial test rig: NPL strong floor - composites testing

There is concern that established test methods using thin coupon specimens are not suitable for thick section design. In addition, the vast majority of composite components experience multi-axial loading in-service, whereas existing composite material test standards are uniaxial in scope. The work builds on previous research on through-thickness properties, ongoing research in the ACLAIM consortium and several recent enquiries on testing of thick sections including the qualification of the largest CFRP mast in the world.
