Abstract
Abstract SiC f /LAS glass-ceramic composites were prepared by hot-press sintering using SiC fibers, SiO 2 , Al 2 O 3 and Li 2 CO 3 powders as starting materials. Mechanical properties, such as strength, toughness, and dielectric properties at X-band microwave frequency of these composites were evaluated. Results showed that both the content and the length of SiC f had significant influences on the dielectric and the mechanical properties of SiC f /LAS composites. The complex permittivity of the composites rose from 12 to 35 for e ′ and 18 to 120 for e ″ at 8.2 GHz with the increasing SiC f content. In addition, the reinforcement and toughening effects of SiC f on the composites were also significant. Our results indicate that the SiC f /LAS composite is a promising material with both the electromagnetic wave absorbing and the load-bearing abilities suitable as structural microwave absorbing and microwave shielding materials.
