Automated Manufacture of Grid Stiffened Panels [PDF]
I European Conference On Multifunctional Structures, 2020 Rib or grid stiffened structures have been investigated for decades, mainly for application in space structures. Grid structures offer the possibility to develop more damage tolerant structures as the network of ribs can provide redundant load paths.
