Abstract
A machine for fabricating three-dimensional interlaced composite components including a frame, a deposition surface, a first set of two or more warp heads, a second set of two or more of warp heads, and a weft inserter. An interlaced composite component including a first set of two or more warp filaments parallel to each other and a first set of two or more weft filaments parallel to each other. Warp filaments are interlaced with, and bonded to, weft filaments s. Warp filaments and weft filaments are interlaced in at least two different weave patterns. Warp filaments and weft filaments are continuous, and the weave patterns transition from one pattern to another.
Claims24
A machine for fabricating three-dimensional interlaced composite components comprising:
- a frame;
- a deposition surface;
- a first set of two or more warp heads adapted to:
- deposit a first set of warp filaments on the deposition surface in a first warp direction;
- and
- move parallel to one another within a first plane;
- a second set of two or more of warp heads adapted to:
- deposit a second set of warp filaments on the deposition surface in a second warp direction;
- and
- move parallel to one another within the first plane;
- wherein the second set of warp heads do not move collinearly with the first set of warp heads;
- and
- a weft inserter adapted to:
- deposit a set of weft filaments on the deposition surface in a weft direction;
- and
- traverse a length of the deposition surface in the warp direction;
- wherein the weft direction is different than at least one of the first and second warp directions.
An interlaced composite component comprising:
- a first set of two or more warp filaments parallel to each other;
- and
- a first set of two or more weft filaments parallel to each other;
- wherein at least a portion of the warp filaments of the first set of warp filaments are interlaced with, and bonded to, at least a portion of the weft filaments of the first set of weft filaments;
- wherein at least a portion of the warp filaments and at least a portion of the weft filaments are interlaced in at least two different weave patterns selected from the group consisting of plain weave, twill weave, and satin weave;
- and
- wherein at least a portion of the warp filaments and at least a portion of the weft filaments are continuous and the weave patterns transition from one pattern to another.
An interlaced composite component comprising:
- a first set of two or more warp filaments parallel to each other;
- and
- a first set of two or more weft filaments parallel to each other;
- wherein at least a portion of the warp filaments of the first set of warp filaments are interlaced with, and bonded to, at least a portion of the weft filaments of the first set of weft filaments;
- wherein at least a portion of adjacent warp filaments of the first set of warp filaments are separated from one another by a warp gap;
- wherein at least a portion of adjacent weft filaments of the first set of weft filaments are separated from one another by a weft gap;
- and
- wherein the warp and weft gaps define one or more openings in the composite component.
