Abstract
A polymer-based composite sandwich includes a core bonded between fiber reinforced resin facesheets. The core includes a truss formed by groups of composite pins held in a low density foam. The pins in each group intersect to form nodes adjacent to one of the facesheets. The ends of the pins extend parallel and are bonded to the facesheets.
