L'objet de l'invention est un châssis composite inférieur de véhicule de type ferroviaire comportant un fond en matériau sandwich comportant deux peaux séparées par une première âme en mousse polymère, caractérisé en ce que le matériau sandwich réalise le fond et le bas des faces du véhicule et est recouvert sur l'une de ses peaux dite peau inférieure destinée à réaliser la face externe du châssis du véhicule d'une seconde âme en mousse revêtue d'un tissu Kevlar formant protection antichoc. The invention relates to a composite lower chassis of a railway-type vehicle, comprising a base made of a sandwich material having two skin layers separated by a first core made of polymer foam, characterized in that the sandwich material makes up the base and the bottom of the sides of the vehicle and in that one of the skin layers, referred to as lower skin layer and intended to form the outer surface of the vehicle chassis, is covered with a second core made of foam coated with a Kevlar fabric, which forms a shook-proofing protection.
