Effects of layer stacking sequence on temperature response of multi-layer composite materials under dynamic conditions

Individual slabs of different types are used to form composites with either 2- or 3-layer of various stacking sequences so as to examine whether stacking order has any influence on the thermal response of the composite samples under dynamic conditions. The excess temperature profile θ(x, t) of a laminated composite slab is first derived by Green’s function (GF) method so that the adiabatic surface excess temperatures for all stacking sequences are mathematically determined to detect the discrepancies between different stacking sequences. The theoretical predictions are then validated with actual experimental data using a custom-made apparatus. The comparisons between the predictions and the experimental data are analyzed in detail and results are discussed. This may be a significant reminder for the multi-layer design of building walls, clothing and other industrial applications.

► The temperature profile of composite slab is derived by Green’s function method.
► The stacking sequence of samples are investigated under dynamic conditions.
► Analytical predictions and experimental data are both applied to this issue.
