Problems solved by technology

Such a carbon fiber heating material (plane heating element) cannot obtain a constant resistance because the coating material cannot be evenly distributed on its entire surface, and the conductive metal cannot maintain a certain order.
Due to the existence of various similar problems, the lifespan of product components varies, and finally brings defects such as poor durability and limited heating temperature
Although planar heating elements that can be used in high-temperature environments (above 200°C) have appeared, in addition to general covering materials, high heat-resistant substances need to be added, so the production cost is relatively high
At the same time, under the same production equipment, the existing technology cannot realize the production of planar heating elements suitable for various temperature conditions.
In addition, in order to cut off other electromagnetic waves generated by the plane heating element, it is necessary to prepare related equipment, which will also lead to an increase in product cost

Embodiment Construction

[0044] Hereinafter, the invention will be described in detail with reference to the accompanying drawings of specific embodiments of the invention. The attached examples are intended to help understanding, and the invention should not be limited thereto. For those who have a certain understanding of the relevant knowledge in this field, the technologies that are clear or easy to understand at a glance will not be described in detail here.

[0045] In order to achieve the above object, the present invention includes the following production stages. Such as figure 1 Shown is the manufacturing process of the planar heating element. That is to say, synthetic fiber filaments and composite carbon fiber filaments are soaked in conductive paint, heated in a heating room at 300°C-500°C, and then placed in a cooling room equipped with a fan to cool down to obtain the coating coating stage of the coated wire (10 ), weaving the above-mentioned covered wire vertically and horizontally,...

Abstract

The invention discloses a carbon fiber heating material and a preparation method thereof. The carbon fiber heating material is formed by weaving composite carbon fiber filaments coated and bonded on common fibers after granules.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a carbon fiber heating material and a preparation method thereof. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside". It is lighter than metal aluminum, but its strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new g...
