Electric heating/Joule heating porous C/C composite material and preparation method and application thereof
The invention belongs to the technical field of composite materials, and particularly relates to an electric heating/Joule heat porous C/C composite material and a preparation method and application thereof.The composite material is composed of, by mass, 10-60 wt% of carbon fibers, 10-60 wt% of an industrial carbon matrix and 10-60 wt% of a biological carbon matrix, and the carbon fibers and the biological carbon matrix adhere to each other through the industrial carbon matrix. The biochar matrix accounts for 10-50 wt%, and the industrial carbon matrix accounts for 5-80 wt%. The electric heating/Joule heat porous C/C composite material is rich in biological carbon matrix, the biological carbon matrix retains a biomass pore structure for adsorption, near-net-size forming under low density is realized, the cost is low, the composite material has excellent electric heating characteristics, adsorption capacity and mechanical strength, the temperature rises quickly after being electrified, a thermal field is uniform and stable, and no aging problem exists; the material can be used for manufacturing an electric heating element for indoor heating and outdoor deicing, and can also be used as a recyclable adsorption element for removing peculiar smell and harmful gas.
本发明属于复合材料技术领域，具体涉及电热/焦耳热多孔C/C复合材料及其制备方法和应用，复合材料为由碳纤维、工业碳基体和生物碳基体组成，碳纤维与生物碳基体之间通过工业碳基体粘连，三者的质量百分比为：碳纤维10‑60wt％，生物碳基体10‑50wt％，工业碳基体5‑80wt％。本发明的电热/焦耳热多孔C/C复合材料富含生物碳基体，生物碳基体保留了生物质孔隙结构用于吸附，而且实现低密度下近净尺寸成型，成本低，具有优良的电热特性、吸附能力和机械强度，通电后升温迅速、热场均匀且稳定、无老化问题，能够用于制作室内取暖、室外除冰的电热元件，也能够用作可循环使用的除异味及除有害气体的吸附元件。
