摘要: A method for designing fiber-composite parts in which part performance and manufacturing efficiency can be traded-off against one another to provide an “optimized” design for a desired use case. In some embodiments, the method involves generating an idealized fiber map, wherein the orientation of fibers throughout the prospective part align with the anticipated load conditions throughout the part, and then modifying the idealized fiber map by various fabrication constraints to generate a process-compensated preform map.

摘要: A cosmetic part is formed via compression molding in a single molding operation with no post processing by forming an assemblage of feed constituents, wherein the assemblage includes plural fiber-bundle-based preforms and one or more resin-only constituents, the latter configured and positioned as appropriate to create resin-rich cosmetic layers where desired on the part.

摘要: A method is disclosed for forming extrudate filament, which consist essentially of fiber, organic binder, and metal and/or ceramic. The extrudate filament can be spooled, or used to form preforms, and/or assemblages of preforms. In further methods, the extrudate filament and/or preforms can be used to fabricate fiber-reinforced metal-matrix or ceramic-matrix or metal and ceramic matrix composite parts, which consist essentially of fiber in a matrix of metal, or ceramic, or metal and ceramic, respectively.

摘要: A system and methods are disclosed for producing components via additive manufacturing. In one embodiment, a three-dimensional geometry is sliced using a slicing plane to obtain a first two-dimensional geometry. A first polyline is generated based on a first skeleton of the first two-dimensional geometry, and a first slender body is generated based on the first polyline. The first slender body is subtracted from the first two-dimensional geometry to obtain a second two-dimensional geometry. A second polyline is generated based on a second skeleton of the second two-dimensional geometry. A first bundle of fibers is produced based on a segmentation of the first polyline and a second bundle of fibers is produced based on a segmentation of the second polyline. A component is produced from the first and second bundles of fibers using an additive manufacturing process.

摘要: Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as “bending regions,” where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).

摘要: A method for making structural foam parts having continuous aligned fibers includes placing an assemblage of fiber-bundle-based preforms in an injection mold, creating a melt flow of resin and, optionally, short, loose fiber, and adding foaming agent to the melt flow. When the foaming agent/melt flow mixture is introduced into the injection mold, the foaming agent foams. The assemblage is structured and positioned so that fibers therefrom adopt a desired alignment and position in the final part. Structural foam fills the remainder of the volume of the part.

摘要: A method for improving the impact resistance of a fiber-composite part includes positioning fibers within an expected impact region of the part, wherein at least a portion of most of the positioned fibers is oriented to be within about 45 degrees of parallel to an impact vector of an impact that occurs at the impact region. At least some of the fibers in the impact region should have relatively high impact resistance, such as glass fiber or aramid fiber, and the matrix in the impact region should have relatively high impact resistance.
