Abstract: A method and system for composite molding, and the method includes additively manufacturing a mold shell that includes a part forming cavity. The method includes filling at least a portion of the mold shell with a strengthening agent. The method includes hardening the strengthening agent to form a mold, and laying-up a composite material on the part forming cavity. The method includes curing the mold to form a composite part.

Abstract: A flow conditioning device includes a body portion having first and second ends and an interior surface defining a channel extending from the first end to the second end, and one or more flow conditioning elements disposed within the channel. Each of the one or more flow conditioning elements is integrally formed with the interior surface of the body portion, and may be a respective flow straightening tube, a flow straightening vane, a hole array plate, a turning vane, a swirling vane, a helical ridge formed along a respective longitudinal segment of the interior surface, or another configuration. The body portion and the one or more flow conditioning elements may be formed by an additive manufacturing process, and may optionally be made of the same material.
