Abrégé

The present invention relates to a composite material for improving metal conductivity and a preparation method therefor. The composite material is formed by compounding n A-B-A structures, wherein A is a graphene fragment layer, B is a metal foil layer, and n is an integer greater than or equal to 2; the graphene fragment layer comprises graphene fragments which are uniformly laid on the metal foil layer. The conductivity of a conventional metal material is at least improved by more than 18%, and the conductivity of the bent metal material is almost the same as the conductivity of the metal material under a normal condition.

Abrégé

A railway intelligent multifunctional travel platform, comprising a travel platform main body (1) and a track wheel driving system (3) and a caterpillar driving system (2) which are respectively connected to the travel platform main body (1), wherein a lifting rotation mechanism (4) is disposed at the bottom of the travel platform main body (1); the caterpillar driving system (2) may raise relative to the track wheel driving system (3) so that the bottom of the caterpillar driving system (2) is higher than or lower than the bottom of the track wheel driving system (3), thereby switching between the caterpillar driving system (2) and the track wheel driving system (3). The described railway intelligent multifunctional travel platform may autonomously carry out a rapid road-rail switch under multiple roadbed conditions.
