A test jig has been developed for the compression of flat plate laminates between parallel dies, making use of an ultra-stiff testing machine. Preliminary experiments have been carried out using this plane strain compression arrangement for a variety of laminates of differing fibre and matrix composition and with different specimen/die geometries. For all of the laminates investigated it was possible to determine a measure of elastic modulus, but strength could only be assessed for unidirectional layups owing to the yield/fracture strength of the steel dies themselves being exceeded for the woven composites. The results obtained compare well with those from the literature using more conventional compression tests.

Texture Characteristics

The development of physically-based models of microstructural evolution during hot deformation of metallic materials requires knowledge of the grain/subgrain structure and crystallographic texture characteristics over a range of processing conditions. A Fe-30wt%Ni based alloy, retaining a stable austenitic structure at room temperature, was used for modelling the development of austenite microstructure during hot deformation of conventional carbon-manganese steels. A series of plane strain compression tests was carried out at a temperature of 950 °C and strain rates of 10 s-1 and 0.1 s-1 to several strain levels. Evolution of the grain/subgrain structure and crystallographic texture was characterised in detail using quantitative light microscopy and highresolution electron backscatter diffraction. Crystallographic texture characteristics were determined separately for the observed deformed and recrystallised grains. The subgrain geometry and dimensions together with the misorientation vectors across sub-boundaries were quantified in detail across large sample areas and the orientation dependence of these characteristics was determined. Formation mechanisms of the recrystallised grains were established in relation to the deformation microstructure.
