Résumé : |
The Boeing 787 Dreamliner is an innovative aircraft that consists of more than 50% carbon fibre reinforced plastics (CFRP) due to these materials' low weight and exceptional strength. Using COMSOL modelling tools, engineers at Boeing research found that a metal foil inserted in a CFRP laminate can provide lightning protection for the aircraft structure. The purpose of this article is to explain how this laminate can be improved to create multifunctional materials that can protect the fuselage from lightning strikes while providing vibration damping and sound absorption effects. |
