Abstract: A method for fabricating a sandwich box impact beam for a vehicle. The method includes fabricating inner and outer facing sandwich structures each including an inner facesheet, an outer facesheet and a micro-truss core therebetween. The micro-truss cores are an ordered three-dimensional network of self-propagating polymer waveguides grown from a photo-monomer resin using a controlled exposure to collimated UV light sources at specified orientations through a plurality of apertures in a mask. The method includes mounting the inner and outer sandwich structures so that an open area is provided therebetween where the inner facesheets face each other across the open area.

Abstract: A hierarchical sandwich box impact beam for a vehicle that includes spaced apart micro-truss sandwich structures defining an open area therebetween. The impact beam includes an outer facing sandwich structure including an outer facesheet, an inner facesheet and a micro-truss core formed therebetween, and an inner facing sandwich structure including an outer facesheet, an inner facesheet and a micro-truss core formed therebetween. One or more structural connecting sections are coupled to the inner and outer facing sandwich structures so as to define the open area between the structures.
