A method was developed to measure the effect of density on certain mechanical and thermal properties of a dense stack of paper. Pieces of paper were stacked in a frame and compressed to different densities by a hydraulic press. The two lateral sides of the stack were smoothened for testing. Thermal conductivity, behavior under cyclic compression loading and in ball indentation test were determined. Thermal conductivity, storage modulus, loss factor depended approximately linearly on the density of the stack.
