Appl. No.:

16/162301

Jon Paul GUNNER - Palos Verdes Estates CA, US

International Classification:

B29C 64/153
B29C 64/209
B29C 64/393

Abstract:

The disclosure relates to additively manufactured (AM) composite structures such as panels for use in transport structures or other mechanized assemblies. An AM core may be optimized for an intended application of a panel. In various embodiments, one or more values such as strength, stiffness, density, energy absorption, ductility, etc. may be optimized in a single AM core to vary across the AM core in one or more directions for supporting expected load conditions. In an embodiment, the expected load conditions may include forces applied to the AM core or corresponding panel from different directions in up to three dimensions. Where the structure is a panel, face sheets may be affixed to respective sides of the core. The AM core may be a custom honeycomb structure. In other embodiments, the face sheets may have custom 3-D profiles formed traditionally or through additive manufacturing to enable structural panels with complex profiles. The AM core may include a protrusion to provide fixturing features to enable external connections. In other embodiments, inserts, fasteners, or internal channels may be co-printed with the core. In still other embodiments, the AM core may be used in a composite structure such as, for example a rotor blade or a vehicle component.

Abstract:

Apparatus and methods for joining nodes, extrusions, and panels are presented herein. Nodes, extrusions, and panels can be joined together using adhesive joining techniques. The adhesive joining techniques can be applied to additively manufactured nodes or extrusions, and sandwich panels. Sandwich panels can be additively manufactured and/or commercial off the shelf (COTS) components. There can be more than one type of a joint formed by the joining techniques. Exemplary types of j oints can use a liquid adhesive in conjunction with a vacuum and/or a film foam adhesive.
