The silica sol slurry with different proportion of short-cut fiber was prepared

and the shell samples were prepared.Effects of fiber addition on the moving viscosity of silica sol slurry

the quality and thickness of moistening slurry were investigated.The results indicate that the movement viscosity of slurry is enhanced by increasing the proportion of fiber

and the movement viscosity is decreased by bimodal distribution.Within a certain range

with increasing in content of fiber

the quality of moistening slurry is increased in an exponential form

and thickness of the shell samples at each direction is increased accordingly.In addition

thickness changes of corner line direction reaches maximum value

and when fiber content is 0.75%

the coating thickness is increased by 0.13 mm.
