Problems solved by technology

Since each carbon fiber bundle in the unidirectional strip structure is independent and electrically disconnected from other carbon fiber bundles, once a carbon fiber bundle fails, if a point is disconnected, it will affect the entire carbon fiber bundle Non-conductive, which seriously affects the heating performance of the electric heating chip, so it is impossible to repair defects such as air pockets and dry spots in the blade

[0060] This embodiment provides a method for preparing a repairable carbon fiber electric heating ice melting chip (electric heating chip for short), and the method includes the following steps:

[0061] Step S1, mixing the glass fiber bundle and the carbon fiber bundle to obtain a chip fiber bundle.

[0062] The electric heating chip is based on glass fiber cloth, and its physical properties are similar to glass fiber cloth. It has the characteristics of regular shape (strip), soft texture and easy processing. It can be processed according to the processing method of glass fiber cloth and processed into Different shapes. Here, the preparation process of the electric heating chip is combined with the preparation process of the glass fiber cloth. The glass fiber bundle provides physical support for the chip, and the carbon fiber bundle provides electrical performance for the chip. When the carbon fiber bundles are sufficiently tough to support each other, the glass fiber bundles ca...

Abstract

The invention provides a reparable carbon fiber electric-heating ice-melting chip and a preparation method thereof. The reparable carbon fiber electric-heating ice-melting chip is prepared in a manner of intersecting carbon fiber bundles in a warp-and-weft direction. Current density of the electric-heating chip is adjusted through adjusting density of the carbon fiber bundles, a heating temperature of the electric heating chip is adjusted. Furthermore arrangement of a bidirectional grid-shaped structure realizes interconnection of carbon fibers through weft-direction carbon fiber bundles, thereby realizing integral electric performance. When a certain carbon fiber bundle fails, heating performance of the electric-heating ice-melting chip is not affected. Furthermore when a plurality of warp-direction carbon fiber bundles are broken, the warp-direction carbon fibers of the whole electric-heating chip can be connected through the weft-direction carbon fiber bundles, thereby effectively reducing de-energization range, reducing non-heating area and ensuring high ice melting effect of the electric-heating chip.

Description

Technical field [0001] The invention belongs to the field of new energy technology and equipment, and specifically relates to a repairable carbon fiber electric heating ice melting chip and a preparation method thereof. Background technique [0002] The collection and utilization of energy by mankind is always closely related to the environment. When the energy harvesting environment is very harsh, such as extreme cold weather and freezing weather, the damage to the energy harvesting equipment is very great. For example, the rotor blades of a wind turbine are used to collect wind energy and must be exposed to the natural environment. Therefore, when designing the blades, not only the influence of its own operation mode must be considered, but also the influence of the environment must be considered. For example, after a large-scale freezing disaster occurred in 2008, it caused heavy losses to many industries, and the wind power industry was no exception. [0003] In order to prev...
