A filter and a method for manufacturing same are disclosed. The filter including nanofibers formed by electrospinning comprises: a base having conductivity; and a nanofiber web formed by attaching the nanofibers on the base. The method for manufacturing the filter by attaching nanofibers on a base comprises the steps of: filling a syringe having a nozzle with a polymer solution, which is a raw material of the nanofibers; applying a +high voltage to the nozzle; and spinning the nanofibers from the nozzle toward the base. The base functions as a counter electrode of the nozzle.

A three-dimensional woven fabric for a composite component and methods of manufacturing such a fabric. The woven fabric has a first region, and a second region and 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 include a plurality of warp fiber tows and a plurality of weft fiber tows. At least a portion of the plurality of reinforcing fiber tows provided in the first region includes bulk fiber tows having a first toughness. At least a portion of the plurality of reinforcing fiber tows provided in the second region includes tough fiber tows having a second toughness. The second toughness of the tough fiber tows is greater than the first toughness of the bulk fiber tows.

A method of manufacturing a woven fabric for a composite component for a turbine engine. The method includes arranging a plurality of warp fiber tows to extend in the warp direction. The plurality of warp fiber tows is arranged in a thickness direction to form a plurality of warp fiber layers and is arranged in a weft direction to form a plurality of warp fiber columns. The method also includes weaving the plurality of weft fiber tows with the plurality of warp fiber tows. The plurality of weft fiber tows includes a multi-layer weft fiber tow. The multi-layer weft fiber tow is woven with a multi-layer portion that extends two or more warp fiber layers of the plurality of warp fiber layers.
