Sol-gel techniques have been used to infiltrate fibrous preforms at room temperature. However, due to large shrinkage during processing, even many infiltration and heat treatment cycles fail to achieve dense composites. Slurries of alumina and silica powders were infiltrated into 3-D woven preforms of mullite based fiber in order to investigate the effects of particle size and size distribution on packing. A well dispersed slurry containing agglomerate-free, submicron-sized particles significantly increased infiltration efficiency and resulted in a high packing density.
