    摘要: Systems and methods are provided for induction welding. One embodiment is a method for induction welding a composite part. The method includes preheating a composite part comprising a matrix of thermoplastic reinforced by fibers, from an ambient temperature to a preheat temperature that is below a melting temperature of the thermoplastic, performing a welding pass of an induction coil over the composite part that initiates while the composite part remains above ambient temperature, and that is performed by generating a welding magnetic field that heats the composite part from the preheat temperature to a welding temperature that equals or exceeds the melting temperature.

    摘要: At least one braided composite layer configured to form a first ply (12, 12') may be provided. A plurality of slit tapes (16) may be arranged and aligned such that each slit tape is adjacent to one another and non-overlapping, to form a second ply (14). A hybrid composite laminate (10) may be formed by stacking a plurality of plies that includes at least one first ply and at least one second ply. Each slit tape may be a steered unidirectional composite slit tape that is aligned along an axis, contour line, or curve of the hybrid composite laminate, a mold/tooling used to shape the laminate, or the resulting composite part. Hybrid composite laminates may be formed by stacking at least one first ply formed of a braided composite layer and at least one second ply formed from a plurality of slit tapes. Composite parts may be formed by consolidating such hybrid composite laminates.

    摘要: 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.
