“…On one hand, the increase of whisker content will lead to the slurry viscosity increase, while the bubbles in the high viscosity slurry cannot be quickly discharged during extrusion and curing, which will lead to the overall porosity (
) increase (as shown in Table 1) and decrease the mechanical properties of the 4SiC w /GP composite. On the other hand, when the whiskers content in the composite reaches about 4 wt.%, the whisker agglomeration will be intensified,
29,44 and the internal defects caused by whisker agglomeration will also lead to the decline of its mechanical properties.…”
