Abstract
Tensile specimens of reinforced epoxide resin of various orientations with respect to the fibre direction, were tested at low strain-rates (3.3×10−4 sec−1) and over a wide range of temperatures (77 to 380K). The rate sensitivities were measured by strain-rate change tests. Activation parameters were determined, by means of which it was possible to correlate the behaviour of composites of various orientations with that of the unreinforced epoxy. Three temperature regions have been established in which it appears that the deformation is controlled by three separate rate-controlling mechanisms.
