Effects on through-the-thickness pressure on the compressive failure of non-crimp fabric composites
(English)Manuscript (preprint) (Other academic)
This paper presents results from an experimental investigation of the influence of a low through-the- thickness pressure on the compressive failure of glass fibre non-crimp fabric composite laminates. Specimens with holes and artificial delaminattons have been manufactured and tested both with and without through-the-thickness pressure, and based on the results obtained it is clear that fibre microbuckling and kinking governs final failure of laminates with open holes, while initiation and propagation of delaminations governs final failure of laminates with artificial delaminations. However, by applying a low through-the-thickness pressure, initiation and propagation of delaminations can be prevented, or at least postponed, and the compressive failure strength thereby substantially improved.
