There are however difficulties in exploiting the full potential of composites materials, in particular under multi-axial loading. The objective of this work is to test the plain- and open-hole strength of thermoplastic AS4D/PEKK-FC UD composite laminates under multi-axial loading. Cruciform specimens are designed for three different layups: (1) Quasi-isotropic [1], (2) Soft, (3) Hard. The biaxial test program covers various biaxial load combinations in tension-tension, tension- compression and compression-compression. For compression loading, a specially designed anti-buckling fixture is developed. Digital Image Correlation (DIC) is performed to determine the strains at failure and fracture process at the center of the cruciform specimen. The experimental data is evaluated to determine the plain- and open-hole biaxial failure envelopes" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Universitat de Girona.
