The thermal contact resistance between polymer composites and aluminum alloy is the main parameters of thermal control design in the field of space and its heat transfer mechanism is very complex. This work is to combine experimental and numerical approaches to evaluate the nature of thermal contact between polymer composites and aluminum alloy. Thermal contact resistance between carbon fiber reinforced epoxy composites and aluminum alloy 380 was measured experimentally. And based on the finite element method, the simulations on heat transfer between polymer composites and aluminum alloy have been performed and compared with experiment results. The results show that the thermal contact resistance between carbon fiber reinforced epoxy composites and aluminum alloy is not negligible and strongly correlated with pressure.

In this study, a thermodynamic model of a laser-assisted automated thermoplastic fiber placement process is developed and validated. The main focus is on modeling the heat transfer into the composite with a laser heat source, the thermal properties of the tape, and the resulting heat distribution in the part, the mold, and the compaction roller. A new integrated analytical method is presented to calculate the energy input of the laser based on the geometric boundary conditions, including first-order reflection and laser shadow. The carbon fiber/polyethersulphone tape is modeled by combining literature properties of carbon fiber and matrix as well as based on experimental data of the tape itself. Also a thermal contact resistance between the tape layers is modeled based on a literature model and own experimental measurements. The created model is discretized and implemented in a 2-D finite difference code. With the help of this simulation, the temperature distribution is calculated during layup. The influence of a possible thermal contact resistance between the composite layers is investigated. Furthermore, an experiment with a thermoplastic fiber placement machine from Advanced Fibre Placement Technology GmbH (AFPT) was conducted in order to evaluate the simulation. The simulation and the experiment show a good agreement and prove that thermal contact resistance between the layers is negligible for the investigation process.
