Zusammenfassung:A polymer-based composite sandwich includes a reinforced core bonded between a pair of composite facesheets. The core includes a truss formed by groups of composite pins held in place by a layer of structural foam. The pins in the groups are radially arranged around nodes. The ends of the pins are splayed and sandwiched between the foam layer and the facesheets.
