Abstract

Preliminary bending and shear tests are performed on a nylon-carbon fibre pre-consolidated cross-ply 0/90/90/0 laminate. The aim is to produce data for use in macro-scale forming simulations. A novel variation on the usual uniaxial bias extension tests is devised. The modifications are designed to create a well-defined boundary condition at the extremities of the test specimen while avoiding transverse squeeze flows due to clamping pressure and undesirable temperature gradients across the test specimen. A variant of the cantilever test is also developed to characterise the temperature-dependent flexural rigidity of the composite as a function of temperature. The cantilever set-up is designed to maximise the rate of testing. Reasonable results are found using both preliminary set-ups, though various causes of error are highlighted and suggestions for future improvements are made.
