Lightweight construction is one of the most efficientways to improve performance of many vehicles ormeans of transport. The weight reduction is desirableto obtain the maximum payload capability, to increasethe speed enhancing the driving performance, or justto reduce the fuel consumption. In this work, novelcarbon fiber reinforced composite cores for sandwichstructures are design, manufactured and tested. Thesedesigns combine the low density of lattice materialsand the relative high strength and stiffness ofhoneycomb cores. The obtained cores are meant to bean attractive alternative to traditional honeycombswith densities less than 50kgm-3, representing arelatively easy to manufacture and weight efficientstructural material, with various potential multifunctional applications such as the ability to supportloads, heat isolation or the possibility to embedelectronics and foams.
