Abstract:
An example method of forming a composite structure is described that includes applying a laminated charge onto an expandable pallet, moving the expandable pallet at a translation rate and relative to a die conveyor that comprises a plurality of die sections, and driving the plurality of die sections on the die conveyor at an angle relative to the expandable pallet so as to drive the plurality of die sections progressively deeper into a recess defined by the expandable pallet and shape the laminated charge into at least part of a shape of the composite structure.

A gripping apparatus includes an impermeable layer defining a vacuum port, a first flow media layer associated with the impermeable layer, and a second flow media layer opposed from the first flow media layer to define a receiving space therebetween.
Abstract:
An ultrasonic cutting machine including a support structure, a positioning device moveable relative to the support structure, a cutting blade connected to the positioning device and a blade cleaning system positioned proximate the support structure, the blade cleaning system including a basin defining an internal volume and an opening into the internal volume, a solvent positioned in the internal volume, a cleaning surface positioned in the internal volume, wherein the cleaning surface is at least partially submerged in the solvent, and a lid positioned over the opening, wherein the lid is automatically displaced from the opening when the cutting blade approximates the basin.
Abstract:
Systems and methods are provided for bi-directional cutters for Automated Fiber Placement (AFP) machines. One embodiment includes a bi-directional cutter for Automated Fiber Placement (AFP) manufacturing. The cutter includes a cutter body that has an upper edge and a lower edge, and has an opening placed between the upper edge and the lower edge that is dimensioned to enable passage of a tow of fiber through the cutter body. The cutter also includes a first blade disposed on the lower edge of the cutter body that is oriented to cut the tow when the cutter is driven downward, and a second blade disposed on an edge of the opening in the cutter body that is oriented to cut the tow when the cutter is driven upward.
Abstract:
Systems and methods are provided for vacuum handling of composite parts. One embodiment is a method for performing vacuum securement of an object. The method includes covering the object with an impermeable membrane, locating a vacuum port at the impermeable membrane, and applying a negative pressure to the vacuum port that offsets air leaks between the impermeable membrane and the object.

Abstract:
A method, system and computer-readable storage medium are provided to facilitate inspection of a composite part during manufacture. In the context of a system, a system for inspecting a composite part during manufacture is provided that includes an inspection system configured to detect an in-process anomaly with respect to a ply of the composite part during placement of the ply. The system also includes a computing system configured to determine part location coordinates of the in-process anomaly detected by the inspection system with respect to the ply of the composite part. The computing system is also configured to map the in-process anomaly to a digital part model based upon the part location coordinates. The system additionally includes a display, responsive to the computing system, configured to present a representation of the digital part model including an indication of the in-process anomaly relative thereto.
Abstract:
An example method of forming a composite structure includes applying a laminated charge onto an expandable pallet, moving the expandable pallet in a linear motion relative to a plurality of rollers, and progressively urging the laminated charge into a continuously expanding recess defined by the expandable pallet using the plurality of rollers. The plurality of rollers are oriented in a serial configuration so as to shape the laminated charge into at least part of a shape of the composite structure.
Abstract:
Described herein are methods and systems for manufacturing composite stringers using independently movable pallets with independent vacuum controls. Specifically, a stringer forming system comprises a base plate and a plurality of sets of pallets (e.g., two or more sets of pallets), slidably coupled to the base plate and forming an adjustable cavity. Each pallet comprises a primary vacuum zone, fluidly connected to a separate vacuum port. The system allows for independent application of a reduced pressure to the primary vacuum zone of each pallet. For example, a reduced pressure is applied only to pallets that are already covered with a composite layup and to pallets that are being covered. Any pallets that are exposed are kept at an ambient pressure and decoupled from a vacuum source, thereby reducing the vacuum leakage through the overall system. As the composite layup is being formed over new pallets, these new pallets are subjected to the reduced pressure.
