The paper addresses the poor thermal conduction performance of carbon fiber composite honeycomb structures and presents a fabrication strategy for a multifunctional carbon fiber honeycomb sandwich structure (MCFHS) that can effectively dissipate heat and bear loads. Theoretical models are developed to predict the thermal conductivity and strength of MCFHS, showing reasonable agreement with experiments. It is shown through experiments that MCFHS has excellent thermal and mechanical performance, with the potential to provide new opportunities for lightweight multifunctional honeycombs.
The poor performance of carbon fiber composite honeycomb structures in thermal conduction is hindering their wider adoption in the high-end heat dissipation field. This paper presents a fabrication strategy for a multifunctional carbon fiber honeycomb sandwich structure (MCFHS) that can effectively dissipate the heat and bear the load. The theoretical models are derived for predicting the thermal conductivity and strength of MCFHS for out-of-plane compression loadings, which show a reasonable agreement with experiment. And experiments for point heat source and surface heat source are designed for researching the thermal dissipation capacity of MCFHS. It proves that MCFHS possess excellent thermal and mechanical performance. And the fabrication strategy has the potential to provide new opportunities for lightweight multifunctional honeycombs.
