This work presents the fabrication routes used to generate unique low density, highly temperature resistant Carbon Nanofiber Foam structures and their inclusion in polymeric shells. The foam was grown from palladium catalyst and ethylene gas employing the constrained formation of fibrous nanostructures process at moderate temperatures. The microstructural characterization of the interwoven fibers that compose the 3D foam was conducted by SEM. We found that an optimal fiber diameter is needed for the nanofibers to generate a mechanically robust foam structure. Epoxy resin or ultra-high molecular weight polyethylene polymeric shells were used to contain the carbon nanofiber foams. The mechanical properties of the core-shell structures were characterized using compression and Izod impact tests at diverse strain rates. The impact energies per weight unit for the diverse formulations are presented. The results suggest that these core-shell structures have great potential for shock absorbing applications were low density is required.
