Three-dimensional woven fabric for a composite component

A three-dimensional woven fabric having a first region, a second region, and an interface region between the first region and the second region, the woven fabric comprising:

• a plurality of reinforcing fiber tows woven together in a three-dimensional pattern such that the woven fabric has a warp direction, a weft direction, and a thickness direction, the reinforcing fiber tows including a plurality of warp fiber tows and a plurality of weft fiber tows, the plurality of warp fiber tows being arranged in the thickness direction to form a plurality of warp fiber layers and the plurality of weft fiber tows being arranged in the thickness direction to form a plurality of weft fiber layers, the plurality of reinforcing fiber tows including bulk fiber tows having a first toughness and tough fiber tows having a second toughness, the second toughness of the tough fiber tows being greater than the first toughness of the bulk fiber tows,
• wherein the plurality of warp fiber tows provided in the first region comprises the bulk fiber tows, the plurality of warp fiber tows provided in the second region comprises the tough fiber tows, and the plurality of warp fiber tows provided in the interface region includes warp fiber tows comprising the tough fiber tows and warp fiber tows comprising the bulk fiber tows, and wherein at least a portion of the plurality of weft fiber tows provided in the second region are tough weft fiber tows comprising the tough fiber tows, and the tough weft fiber tows are directed to a surface of the woven fabric and terminate in the interface region.
