Abstrakt: Aluminum-containing silicon carbide (SiC/Al) fibers were fabricated by electrospinning a polyaluminocarbosilane (PACS) solution followed by the pyrolysis of the electrospun fibers at 1200 oC in a nitrogen atmosphere after air-curing at 200 oC. The optimum electrospinning conditions were a 0.9 g/mL PACS solution with 20%DMF/20%THF/60% toluene composition, a 20 kV spinning voltage, a 2 mL/h injection speed and a 10 cm receiving distance. The obtained SiC/Al fibers have a diameter in the range of 0.7~1.5 m.
