    Abstract: A system to aid in design for manufacturing an object includes a processor and a memory configured to store instructions. The processor is configured to receive first data representing a design of the object to be manufactured and second data representing a machine-learning model. The processor is configured to execute the instructions to generate third data using the first data and the second data. The third data indicates at least one of a modification to the design of the object or process conditions for production of the object. The processor is configured to send the design of the object, the process conditions, or both, to a manufacturing tool to enable production of the object. The machine-learning model is representative of production data and based at least partially on one or more of: object features, process parameters, environmental factors, and quality data.

    Abstract: A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head connected to and moveable by the support. The print head may have an outlet configured to discharge a continuous reinforcement at least partially coated in a matrix. The system may also include at least one doser located inside the print head and configured to at least partially coat the continuous reinforcement with the matrix, a sensor located downstream of the at least one doser and configured to generate a signal indicative of an amount of matrix coating the continuous reinforcement, and a controller in communication with the sensor and the at least one doser. The controller may be configured to direct a feedforward command to the at least one doser to cause the at least one doser to advance matrix toward the continuous reinforcement during passage of the continuous reinforcement through the print head, and to selectively adjust the feedforward command based on the signal.

    Abstract: Compositions including a polyimide and one or more thermally conductive fillers, and compaction rollers for an automated fiber placement machine incorporating the compositions are provided. The polyimide may be a polymeric reaction product of a dianhydride and one or more diamines. The one or more diamines may include a fluorine-containing alkyl ether diamine. The one or more thermally conductive fillers may include one or more of a carbon-based filler, boron nitride, a metal, or combinations thereof. The compositions may have a thermal conductivity of from about 0.2 to about 50 Watts per meter Kelvin (Wm−1 K−1).

    Abstract: A method of manufacture of a composite component is provided, the method comprising the steps of providing two layers of pre-preg composite material, one of which has an edge adjacent a surface of the other. Pressure and, optionally, vibrational energy is applied to the edge to thereby smooth the ply drop.

    Abstract: An automated fiber bundle placement apparatus including a placing head having a pressing device, and a multi-jointed robot. The pressing device includes a pressing part, a pressing mechanism having a drive device, and a drive control device. The drive control device includes a drive command unit configured to output a drive command corresponding to a contact width of a placement die with the pressing part, the contact width being a length in the width direction of a part of the placement die facing in parallel to a contact range of the pressing part during pressing against the placement die, and is configured to control drive of the drive device to apply a pressing force corresponding to the drive command to the pressing part.

    Abstract: An automated fiber-placement method comprises delivering a first quantity of pulsed energy to first discrete portions of at least one fiber-reinforced tape strip, and delivering a second quantity of pulsed energy to second discrete portions of at least the one fiber-reinforced tape strip, alternating with the first discrete portions. The first quantity of pulsed energy heats the first discrete portions to a first temperature. The second quantity of pulsed energy heats the second discrete portions to a second temperature. The automated fiber-placement method further comprises laying down at least the one fiber-reinforced tape strip against a substrate along a virtual curvilinear path, such that (i) at least the one fiber-reinforced tape strip is centered on the virtual curvilinear path, and (ii) the first discrete portions are transformed into discrete tape-regions, geometrically different from the first discrete portions.

    Abstract: A method and system for assisting in the manufacture of composite parts such as those used for various high-strength assemblies such as aircraft wings, vertical stabilizers, racing car shells, boat hulls, and other parts which are required to have a very high strength to weight ratio. The system uses laser technology to measure the resultant surfaces of a first manufactured composite part. A computer system analyzes and compares the as-built dimensions with the required production specifications. Supplemental composite filler plies are designed including shape and dimensions. These plies are nested together into a single composite sheet and manufactured to minimize wasted material. The plies are then cut out and applied to the first part guided by a laser projection system for locating the plies on the part. The part is then re-cured. The final assembly is then re-measured for compliance with production dimensions.
