Abstract In making SiC precursor fiber
using a powder coated route, the binder, poly
(methyl methacrylate) was used, and the solvent is acetone. The viscosity of the binder was tested by
viscometer, and the critical concentration of the binder is 0.03 g/mL. The content of residual
substance of the binder at different temperatures and pressures was test by chemical analysis.
The volatility kinetics of the binder was also studied. The temperature for the binder
decomposition is about 230 ℃, the velocity reaches its
maximum at about 350 ℃, and the
decomposition completed under 400 ℃.
The decomposition and transgression velocities
increase when temperature is increased
under the same pressure. The transgression velocity
reduces when pressure is increased at the same
temperature. The process of making
uniform precursor was found by a uniformity design method.
