Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a temperature-controllable electric heating long glass fiber reinforced material and a preparation method and application thereof. Background technique [0002] Electric energy is an indispensable energy source in today's social production activities and daily life. Especially since the 21st century, the consumption of electric energy has grown rapidly. Electric heating fields such as hot water cooking. [0003] At present, the Joule resistance heating technology is the most widely used, that is, when the current passes through the resistance heating element with limited conductivity, the resistance loss in the material will convert the electrical energy into heat energy. The resistance heating element often uses nickel complex alloys. In addition to high melting point metals such as Fe-Cr-Al series, Ni-Cr series, W, and Mo, inorganic heating elements such as silicon...
