Abstract

The invention discloses a three-dimensional multilayer electric heating composite material with filled structures and fabric structures and a method for preparing the three-dimensional multilayer electric heating composite material. The three-dimensional multilayer electric heating composite material comprises three-dimensional woven fabrics with spacing structures. The three-dimensional woven fabrics with the spacing structures are formed by a protective layer, an electric heating layer, a heat-insulation layer and a support layer which are sequentially subjected to composition, and the various layers are integrally bound by spacing yarns. The method includes arranging various layers of warp yarns and spacing yarns according to yarn selection schemes; starting weft insertion devices, leading in various layers of weft yarns and reeling the weft yarns by motors; leading in heat-insulation filled materials; interweaving the spacing yarns and integrally weaving the various layers of warpyarns and weft yarns. The three-dimensional multilayer electric heating composite material and the method have the advantage that the three-dimensional multilayer electric heating composite material prepared by the aid of the method is simple in structure and good in structural integrity, is light, has the properties of damp-heat aging resistance, impact resistance and the like and can be widely applied to the civil and military fields.

Description

technical field [0001] The invention relates to a three-dimensional multilayer filling structure electrothermal composite material and a preparation method thereof, belonging to the technical field of composite material preparation. Background technique [0002] With the continuous improvement of people's living standards, the requirements for the living environment have not only to meet the basic living conditions, but also to create a comfortable and comfortable living environment, put forward higher requirements for the indoor environment, and require the indoor environment to meet the temperature, Humidity, indoor wind speed, pollutant concentration, etc. are required to be controlled within a certain range. Based on the regulation of indoor temperature, especially the problem of indoor heat preservation in winter, electric heating products develop rapidly and gradually appear in people's daily life. The electric heating products on the market mainly include: electric he...
