Supported by 2D and 3D Imaging Methods Investigation of the Influence of Fiber Orientation on the Mechanical Properties of the Composites Reinforced with Fibers in a Polymer Matrix
Abstract
The aim of this study was to examine the behavior of the carbon fiber reinforced polymer (CFRP) compositesdepending on the fiber orientation and to understand the influence of microstructural discontinuities on mechanicalproperties. For the tests 210 gsm prepreg composite and 200 gsm carbon fabric with polymer matrix have beenused. Samples were structured and later examined according to the ASTM-D3039 and ASTM-D3878 (equivalentsare ISO 20975, ISO 527-4 and ISO 527-5). Accordingly, to the number of layers, three ways of the fibers arrangingin relation to the applied force were used. Mechanical properties were determined in a static tensile test. The resultsof imaging studies, which included analyzes of Digital Image Correlation, Computed Tomography and ScanningElectron Microscopy, showed structural discontinuities, specific stress distribution and propagation of stressesdepending on the production technology, which were correlated with the obtained strength results. The source ofthe gradual development of the degradation of the composite structure was observed in local microdamages andmicrocracks. As a result of a sub-critical crack growth within the resin matrix material, the defects are subject to a complex, multi-axial stress field on the micro-scale, even if the globally applied force is axial. Samples in whichthe load was applied along the axis of the fibers behave like an elastic material, while samples, where the force isapplied at an angle to the axis of the fibers, tend to behave like an elastic-plastic material.
