Abstract
(EN)
Provided in the present invention is a high-temperature-resistant electrothermal fiber, the high-temperature-resistant electrothermal fiber comprising a fiber inner core and a microcrystalline graphite layer coated outside of the fiber inner core, wherein the fiber inner core employs high-temperature-resistant fiber. The microcrystalline graphite layer is deposited on the surface of the fiber inner core by means of a chemical vapor deposition method, and the thickness of the microcrystalline graphite layer is preferably smaller than 10 micrometers. Compared to carbon fiber electrothermal materials, the toughness and air permeability of the electrothermal fiber according to the present invention may not only be increased due to an intermediate fiber filament and the structure in which the outer side of the intermediate fiber filament is coated with microcrystalline graphite, but the thermal radiation area thereof may also be improved, thereby further improving the thermal conversion efficiency and achieving nearly 100% electrothermal conversion efficiency.

La présente invention concerne une fibre électrothermique résistante aux températures élevées, la fibre électrothermique résistante aux températures élevées comprenant une âme interne de fibre et une couche de graphite microcristallin revêtue à l'extérieur de l'âme interne de fibre, l'âme interne de fibre utilisant une fibre résistante aux températures élevées. La couche de graphite microcristallin est déposée sur la surface de l'âme interne de fibre au moyen d'un procédé de dépôt chimique en phase vapeur et l'épaisseur de la couche de graphite microcristallin est de préférence inférieure à 10 micromètres. Comparativement aux matériaux électrothermiques en fibre de carbone, la solidité et la perméabilité à l'air de la fibre électrothermique de la présente invention peuvent être augmentées grâce à un filament de fibre intermédiaire et grâce à la structure dans laquelle le côté extérieur du filament de fibre intermédiaire est revêtu de graphite microcristallin. En outre, la zone de rayonnement thermique peut également être améliorée, ce qui permet d'améliorer encore plus l'efficacité de conversion thermique et d'obtenir une efficacité de conversion électrothermique de presque 100 %.
