Abstract

The invention discloses a composite material skin and a preparation method thereof; the composite material skin includes an upper fiber reinforced layer, a heatable polyimide thin film and a lower fiber reinforced layer; the upper fiber reinforced layer and the lower fiber reinforced layer are adhered to the upper surface and the lower surface of the heatable polyimide thin film respectively. The composite material skin provided by the invention has the advantages of light weight, uniform heat generation, high heat generation efficiency, adoption of human safe voltage for heating, safety, reliability and the like; at the same time, the composite material skin can be conveniently laid on conventional interior trim parts, and meets the heating function of the interior trim parts without affecting a conventional spatial layout. A solution can be provided for lightweighting of advanced passenger cars, saloon cars, high-speed railways and various rail transit vehicles, and at the same time, the space of an air conditioner hot air system is saved.

Description

technical field [0001] The invention relates to the technical field of composite materials used in the rail transit field, in particular to a heatable polyimide-fiber reinforced composite skin and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy, the problem of energy shortage has become more and more prominent. New energy, low carbon, pollution-free, energy saving and consumption reduction have become the urgent development direction of the country. At present, with the vigorous development of my country's rail transit industry, passengers have higher and higher requirements for the comfort, safety and energy saving of vehicles. The current vehicle heating system has problems such as air pollution, high environmental noise and high energy consumption. Contents of the invention [0003] In view of this, the object of the present invention is to provide a composite material skin and its preparation metho...
