Abstract
A method of fabricating a composite component, includes forming a fibrous preform by forming a first ceramic particle layer over a first textile layer, the first ceramic particle layer having a first group of ceramic particles, disposing a second textile layer over the first ceramic particle layer, forming a second ceramic particle layer over the second textile layer, the second ceramic particle layer having a second group of ceramic particles, and disposing a third textile layer over the second ceramic particle layer. The method further includes densifying the fibrous preform.

A method of fabricating a composite component, comprising:
- forming a fibrous preform by:
- forming a first ceramic particle layer over a first textile layer, the first ceramic particle layer having a first group of ceramic particles comprising a first volume of boron carbide powder;
- disposing a second textile layer over the first ceramic particle layer;
- forming a second ceramic particle layer over the second textile layer, the second ceramic particle layer having a second group of ceramic particles comprising a second volume of boron carbide powder;
- disposing a third textile layer over the second ceramic particle layer;
- and
- forming a third ceramic particle layer over the third textile layer, the third ceramic particle layer having a third group of ceramic particles comprising a third volume of boron carbide powder, wherein the first group of ceramic particles has a first average particle size, the second group of ceramic particles has a second average particle size, and the third group of ceramic particles has a third average particle size, the second average particle size being less than the first average particle size and the third average particle size being less than the second average particle size;
- and
- densifying the fibrous preform.
