Abstract The die--swell mechanism of polycarbosilane(PCS) melt for a spinneret with Y--shaped orifice and the effect of die swelling of PCS on the profile degree ($PD$) of Y--shaped SiC were investigated. For a spinneret with circular holes, the die--swell ratio was in the range of 1.02$\sim$1.15, while for a spinneret with Y--shaped orifices, the ratio is 1.02$\sim$1.43. The die--swell ratio for a spinneret with Y--shaped orifices was about 15\% higher than that with circular holes in the same forming condition. The asymmetric distribution of shear stress in the circumference of the Y--shaped orifice and the different shear stress in the orifice profiles were the fundamental reasons for the increase of the die--swell ratio for the Y--shaped orifice. In comparison with the $PD$ of the orifice, there was a reduction of 10\%$\sim$20\% in the $PD$ of the fibers.

Key words: inorganic nonmetallic material die-swell ratio Y-shaped SiC fibers profile degree
