Abstract: A sandwich structure configured to be secured with a mechanical fastener includes a core assembly, which includes a polymer component configured for supporting a mechanical fastener connector insert. The core assembly further includes an open cellular component formed from a plurality of self-propagating photopolymer waveguides positioned around the polymer component, wherein a first portion of the plurality of self-propagating photopolymer waveguides is secured to and extends from the polymer component. Further included is a first face sheet secured to a first side of the core assembly, wherein the first portion of the plurality of self-propagating photopolymer waveguides has a distal end spaced apart from the polymer component and secured to the second face sheet.
