Abstract:
Adapting to extremely harsh service environments is an unavoidable challenge for microwave absorption materials. In this paper, C/PyC/SiC composites were prepared by a vacuum impregnation, curing and cracking process with various preparation cycles, and the stress-strain curves were further discussed. The results show that after three cycles, the C/PyC/SiC composite showed significantly enhanced mechanical properties of 83.59 MPa at around 35.00% strain, and it also possessed the best overall electromagnetic microwave absorption performance, with a minimum reflection loss value of -46.04 dB at 16.06 GHz and 1.90 mm of thickness. All in all, we have introduced an innovative method for fabricating electromagnetic microwave-absorbing materials capable of withstanding harsh environmental conditions.
