摘要： A preform tooling arrangement includes a base plate comprising a male die surface and a stripper plate comprising a female die surface. A plurality of perforations are disposed in the base plate and/or the stripper plate. The stripper plate is moveable with respect to the base plate. The preform tooling arrangement is configured to receive a fibrous preform between the male die surface and the female die surface. The preform tooling arrangement is a dual-purpose fixture configured to accommodate z-needling and densification, all while the fibrous preform remains in the same fixture (i.e., the preform tooling arrangement). The perforations are configured to receive one or more textile needles for through thickness reinforcement of the fibrous preform.

摘要： An end effector for the through thickness reinforcement of a fibrous preform includes a plurality of spray nozzles configured to direct a needle cleaning fluid to a needle to clean resin from the needle between through thickness reinforcement operations. The plurality of spray nozzles may extend from a presser foot toward the needle. The needle cleaning fluid may contact the needle while the needle or the presser foot move (e.g., translate and/or rotate) with respect to the other of the needle or the presser foot. The plurality of spray nozzles can be incorporated into the end effector. The plurality of spray nozzles can be incorporated into a needle cleaning station into which a portion of the robotic end effector can be moved for cleaning the needles.

摘要： A shape forming tool for pre-carbonization compression of a fibrous preform includes a female forming tool comprising a die recess, a first die half configured to be received by the die recess, a second die half configured to be received by the die recess, an expander tool coupled between the first die half and the second die half. The expander tool is configured to move the first die half laterally toward a first side of the female forming tool away from the second die half to compress the fibrous preform between the first die half and the female forming tool. The expander tool is further configured to move the second die half laterally toward a second side of the female forming tool away from the first die half to compress the fibrous preform between the second die half and the female forming tool.

摘要： A method for selective needling on a fibrous preform includes performing a through thickness reinforcement process on the fibrous preform and varying a needle density, a needle angle, and/or a needle penetrating depth during the through thickness reinforcement process such that a first needle density, a first needle angle, and/or a first needle penetrating depth of a first zone of the fibrous preform is greater than a second needle density, a second needle angle, and/or a second needle penetrating depth of a second zone of the fibrous preform. The method can further include identifying expected interlaminar stress throughout the fibrous preform and varying the needle density, needle angle, and/or needle penetrating depth in accordance with a magnitude of the expected interlaminar stress.

摘要： A shape forming tool for pre-carbonization compression of a fibrous preform includes a female forming tool comprising a die recess, a support structure moveable with respect to the female forming tool, and at least one bladder coupled to the support structure and configured to be received into the die recess. The support structure is configured to move the bladder(s) with respect to the female forming tool. The bladder(s) is/are configured to be inflated to apply a compressive force to compress and form a fibrous preform between the bladder(s) and the female forming tool.

摘要： A manufacturing method is disclosed herein. The method includes arranging a preform with a plurality of clamping assemblies, the plurality of clamping assemblies disposed along ends of the preform; and forming the preform into a shaped body, the forming including: incrementally tensioning the preform around a surface of an inner mold line using the plurality of clamping assemblies; and drawing the preform into a set of forming beads of the inner mold line.

摘要： Systems and methods for performing an in-tool carbonization process including exotherm control on a fibrous preform includes one or more temperature control channels disposed in a heat treatment tooling fixture. A fluid may be moved through the temperature control channel(s) for controlling a temperature of the fibrous preform as the fibrous preform is heated during carbonization. A fluid source, a valve arrangement, and one or more heaters can be controlled for regulating a temperature and/or flow rate of fluid through the temperature control channel(s). In this manner, the fibrous preform may be uniformly brought to an exotherm temperature range such that shrinking of the fibrous preform occurs simultaneously and uniformly throughout the fibrous preform. The temperature control channels can be grouped by geographic location for zoned temperature control. The carbonization process can be performed using a single composite fixture or using both metallic and composite fixtures.

摘要： An end effector for needling a fibrous preform includes a body (or head), a plurality of articulating presser feet mounted to the body and moveable with respect to the body, and a plurality of articulating needles mounted to the body and moveable with respect to the body. The needles may be configured to move between an extended position and a retracted position. The presser feet may be configured to move between an extended position and a retracted position. The end effector presser feet may conform to complex geometries of a fibrous preform. The end effector may control needling depth, needling density, applied tension and/or pressure on the fibrous preform, and needle angle.

摘要： A manufacturing method is provided. A preform is arranged over a surface of an inner mold line. The preform is folded over sides of the inner mold line. An end of the preform is clamped to a floating plate using a bladder-activated clamp. The floating plate is translated in a first direction to tension the preform into a shaped body. A plurality of compressing bladders are activated to apply compressive forces to the preform.
