Zusammenfassung:This work fabricated carbon fiber (CF)-reinforced foamed cement-based composites with excellent electromagnetic wave (EMW) absorption performance and flexural properties. The reinforcement effect and mechanism of different CF dosages were studied. The results show CF significantly improves the EMW absorption properties of foamed cement-based materials. The balancing of impedance matching and loss capacity by changes in CF doping is the main reason for the excellent EMW absorption properties with absorption bandwidths of 10.96 GHz (
