Methods for embedding fasteners in an open cellular sandwich structure

摘要

Methods of embedding at least one fastener in a sandwich structure having an ordered three-dimensional microstructure core provided between a pair of facesheets. The method includes attaching the at least one fastener to a first facesheet. The method also includes irradiating a volume of photo-monomer in a reservoir with light beams to form an ordered three-dimensional microstructure core around the at least one fastener. The method also includes attaching a second facesheet to the ordered three-dimensional microstructure core to form the sandwich structure. The fasteners embedded in the sandwich structure are configured to facilitate attachment of the sandwich structure to another structure.

1. A method of embedding at least one fastener in a sandwich structure concurrently with fabrication of an ordered three-dimensional microstructure core of the sandwich structure, the method comprising:
attaching the at least one fastener to a first facesheet; irradiating a volume of liquid photo-monomer in a reservoir surrounding the at least one fastener with light beams to form the ordered three-dimensional microstructure core having a plurality of polymer optical waveguides around the at least one fastener; and attaching a second facesheet to the ordered three-dimensional microstructure core to form the sandwich structure.
