摘要： Additive manufacturing fiber tows comprise a bundle of elongate fibers. Bindments, which may include particles, elongated bindment segments, coating segments, and/or encircling bindments are interposed among the plural elongate fibers to provide interstitial regions among the plural elongate fibers and the bindments. Methods of additively manufacturing an article with a configuration comprise dispensing the additive manufacturing fiber tow with bindments in multiple successive courses in the configuration to additively manufacture the article. The methods may include fixing the bindments together to hold the article in the configuration with the interstitial regions among the plural elongate fibers and the bindments. A solidifiable matrix material may be applied to the article, including to the interstitial regions, and the solidifiable matrix material may be solidified to form a finished article.

摘要： A feedstock line comprises elongate filaments, a resin, and optical direction modifiers. The resin covers the elongate filaments. The optical direction modifiers are covered by the resin and are interspersed among the elongate filaments. Each of the optical direction modifiers has an outer surface. Each of the optical direction modifiers is configured such that when electromagnetic radiation strikes the outer surface from a first direction, at least a portion of the electromagnetic radiation departs the outer surface in a second direction that is at an angle to the first direction to irradiate, in the interior volume of the feedstock line, the resin that, due at least in part to the elongate filaments, is not directly accessible to the electromagnetic radiation, incident on the exterior surface of the feedstock line.

摘要： Multi-part filaments for additive manufacturing comprise an elongate filament body. The elongate filament body comprises a first body part extending longitudinally along the elongate filament body, and a second body part extending longitudinally along the elongate filament body. The first body part comprises a first material, and the second body part comprises a second material. One of the first body part and the second body part is more rigid than the other of the first body part and the second body part and is sufficiently rigid to print self-supporting structures from the multi-part filament.

摘要： Systems for cure control of additive manufacturing comprise a build volume, a curing energy source, and a controller. The curing energy source is configured to actively deliver curing energy to discrete sections of a part as it is being additively manufactured. The controller is programmed to direct delivery of curing energy to impart desired cure properties to the discrete sections and/or according to predetermined cure profiles for the discrete sections. Methods of additively manufacturing a part comprise additively building a part from a feedstock material, and actively curing discrete sections of the part as it is being additively built to impart desired cure properties to the part and/or desired cure profiles to the part.

摘要： Systems and methods for additively manufacturing composite parts are disclosed. Systems comprise at least a feedstock source and a feed mechanism. The feedstock source comprises a plurality of pre-consolidated tows, with each pre-consolidated tow comprising a fiber tow within a non-liquid binding matrix. In some systems, a tow combiner receives at least a subset of the plurality of pre-consolidated tows from the feedstock source and combines the subset of the plurality of pre-consolidated tows to define a macro tow. The feed mechanism moves the subset of the plurality of pre-consolidated tows from the feedstock source and into the tow combiner and moves the macro tow from the tow combiner. Methods according to the present disclosure comprise combining a plurality of pre-consolidated tows to define a macro tow, and dispensing the macro tow in three dimensions to define a composite part.

摘要： A self-sealing bladder may automatically seal a puncture wound formed in a bladder wall thereof, such as due to being perforated by a projectile. Self-sealing bladders may be used in containers, such as fuel tanks, in order to prevent loss of fuel or other fluid from the container. Self-sealing bladders may contain a sealant material contained within one or more localized reservoirs formed within the bladder wall, the sealant material being pressurized within the bladder wall such that a localized reduction in pressure due to a perforation in the bladder wall causes the sealant material to migrate to the perforated site, whereupon the sealant material hardens, thereby sealing the wound. The localized reservoirs may include one or more channels and/or connecting layers extending therefrom and in fluid communication therewith, to facilitate migration of the sealant material away from the localized reservoirs and towards the perforated portion of the bladder wall.
