Abstract [en]

This thesis work was carried out as a part of the Up in the Blue-project, which aims at introducing Oxeon´s TeXtreme ® fabrics into the aerospace industry. The purpose of this study was to assess the mechanical performance of the TeXtreme composite material, focused on the micro and meso level.On the micro level a method for determining the fibre volume fraction using image analysis was developed, with satisfactory accuracy.On the meso level the weave geometry of the TeXtreme fabric was modelled using finite element methods to investigate stiffness and strength. The predicted initial damage formation for the TeXtreme fabric loaded in tension is matrix cracks in the 90°-fibre bundle. In compression the predicted failure mode is fibre kinking in the 0°-fibre tow.Tensile and compressive properties (stiffness and strength) of both TeXtreme unidirectional and TeXtreme fabric composites were tested according to composite standards, and the measured properties were used in the numerical modelling. The tested specimens were studied in an optical microscope to investigate the damage formation.
