PURPOSE:To manufacture the titled light weight wire, etc. superior in strength, elasticity, by spraying or vapor depositing metal in case of necessary to a prearranged SiC fiber bundle, then dipping it into molten metal to which ultrasonic vibration is applied. CONSTITUTION:Molten Al is sprayed to the SiC fiber bundle 2 prearranged by a fiber bundle arranging apparatus 1 to fix parallelism of each fiber. Next, the bundle 2 is introduced into a vessel 6 fed with molten Al5 to permeate it therein. In this case, ultrasonic of 19-20kHz frequency is oscillated by an oscillator 8, and a vibrator 9 is vibrated at the frequency. Said vibration is transmitted to a phon 10 having an air or water cooled insulating jacket 11 between the vibrator 9 and the phon 10. A length L of the phon is that expressed by a formula ( I ), the phon is dipped into the Al 5, ultrasonic vibration is applied thereto to permeate is thoroughly into SiC fiber bundle, and preform light wire, etc. for FRM superior in strength and elasticity is manufactured. |
