SiC Micro-Threads Prepared within the Carbon Fiber Felt
Polyacrylonitrile (PAN) based carbon fiber felt which contains abundant various SiC microthreads and some other microstructures was prepared through sintering the pretreated felt at high temperature at low nitrogen pressure.XRD,SEM,TEM,HRTEM analyses for the sintered felt were carried out to study its components and microstructures.There are SiC nanothreads,SiC submicron threads,SiC micron threads and a few SiO2 two-or three-dimensional microstructures (possibly intermix with the similar form of SiC) existed within the inner hollow spaces of the felt.The complex permittivity,complex permeability of the sample in the X-band frequency range were obtained.
