Abstract

Erosive wear phenomena have been studied for more than half a century and it is well known that high-speed impacts generate very high strain rates. However, the research so far have used quasi-static data to correlate the erosive wear with material properties. There is need for generating high rate materials properties for correlation with wear properties and this is the goal of this paper. We seek to establish the relationship between erosive wear and high strain rate compressive behaviour of carbon-fibre reinforced epoxy composites. The composite materials include: 3D Orthogonal, 3D Layer-to-Layer, BD Tufted and BD non-crimped architectures. A compression split Hopkinson Bar was used to test the composites at high rates. In this paper, the stress-strain curves and further mechanical properties of the test composites were determined at varying rates. The authors also obtained erosive wear rates of the composites using a centrifugal erosion tester. The paper conclude that mechanical properties at high rates correlate more to the underlining mechanical response of erosive wear. Microscopy studies of tested specimens reveal that erosive wear damage is more dominant at high strain rates. The results from this study should inform accurate description/modelling of wear behaviour of the chosen composite materials.
