Concept investigation of a lightweight composite lattice morphing wing

D Keidel, U Fasel, P Ermanni - AIAA Journal, 2021 - arc.aiaa.org
This work introduces a novel structural concept for morphing wings, based on carbon-fiber
reinforced polymer (CFRP) lattice structures. Conventional wing spars and ribs are replaced …

A failure mechanics and strength optimization study for patched laminates

R Kussmaul, M Zogg, P Ermanni - Composite Structures, 2019 - Elsevier
Fiber patch placement (FPP) is a manufacturing technique for variable-stiffness composites
structures. Using FPP, a component is assembled from a multitude of discrete fiber patches …
