Abstract
The mechanical behaviour of carbon-fibre-composite specimens of fibre volume fractions from 30 to 60% and various fibre orientation has been investigated experimentally for compression loading up to 200 MN m−2 and duration approximately 30 μs. A split Hopkinson pressure bar technique has been employed with an optical recording method to monitor the displacements of the end faces of the cylindrical specimen. For specimens loaded along the fibre direction the deformation is characterized by two approximately linear regions of different slope, and an empirical relation has been derived between volume fraction and the modulus obtained from the initial slope.
