A machine and method are presented for continuously forming a woven composite with controllable internal fabric geometry. The machine may include one or more spools for dispensing one or more warp filaments, a roller assembly configured to receive a composite weave, a warp rack having warp heads for engaging the warp filaments and vertically adjusting position to dynamically create a weave pattern in response to the insertion of one or more weft filaments by a weft inserter stack.

Systems and methods for continuous fabrication of woven composite materials

A machine and method are presented for continuously forming a woven composite with controllable internal fabric geometry. The machine may include one or more spools for dispensing one or more warp filaments, a roller assembly configured to receive a composite weave, a warp rack having a plurality of warp heads for engaging the warp filaments and vertically adjusting position to dynamically create a weave pattern in response to the insertion of one or more weft filaments by a weft inserter stack.

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. 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.

Interlaced three-dimensional printed composites and machines for fabricating same

A machine and method are presented for producing interlaced composite components. The method includes: depositing a first one or more warp filaments onto a deposition surface in a first linear direction, inserting, on top of the first one or more warp filaments, a first one or more weft filaments in a second linear direction, where the second direction is in the same plane as the first one or more warp filaments but is not parallel to the direction of the first one or more warp filaments, depositing, on top of the one or more first weft filaments, one or more second warp filaments in first linear direction, where the second one or more warp filaments are not collinear with the first one of more warp filaments, and inserting, on top of the second one or more warp filaments, a second one or more weft filaments in the second direction.
