Abstract Infrared and radar wave stealth primarily enhance the concealment of targets by reducing the signals of infrared radiation and radar echoes. A dual functional cement-based composite material that combines infrared and radar wave stealth was developed by encapsulating phase change materials (PCM) with carbon black (CB) as phase change units (PCU) and combining them withexpanded perlite-magnetic particle/cement composite materials. The electromagnetic wave (EMW) absorption and thermal properties of samples were tested and simulated. The experimental results indicate that CB has a minimal impact on the phase change temperature of PCMs, with only a 1.9% decrease in latent heat. After 500 cycles of heating and cooling, the PCMs retain approximately 78.3% of fusion latent heat, demonstrating good cycle stability. The PCU and expanded perlite can enhance the EMW absorbing performance of cement-based materials, with adjustable reflection loss ranging from -5 dB to -15 dB. The PCU reduces the external surface temperature of the sample by absorbing a significant amount of heat, thereby weakening infrared radiation. The addition of PCMs increases the thermal conductivity of cement-based composites. However, the high thermal storage density of PCU and low thermal conductivity of expanded perlite contribute to a more significant insulation effect in cement-based composites, resulting in a reduction of infrared radiation signal. The simulation results express that magnetic loss only occurs in the cement matrix, and the PCU affects the EMW absorbing performance of cement-based materials through resistance loss. The heat conduction is hindered at the PCU, causing the conduction heat flux to bend at the edge of the PCU. After the phase change is complete, the heat distribution tends to be uniform. Therefore, cement-based composite materials can achieve multi-band stealth in different complex environments, such as infrared and radar waves, by dissipating EMW and absorbing target heat, respectively, thereby reducing radar echo signals and infrared radiation.
