Description

technical field [0001] The invention relates to the technical field of surface temperature prediction of carbon fiber heating wires, in particular to a method for predicting the surface temperature of carbon fiber heating wires after heating. Background technique [0002] Carbon fiber is mainly made of carbon fiber reinforced plastics, a composite material used to apply carbon fiber is a fibrous carbon material. It is a new type of material with higher strength than steel, lower density than aluminum, more corrosion resistance than stainless steel, higher temperature resistance than heat-resistant steel, and conductivity like copper, with many valuable electrical, thermal and mechanical properties. . The aircraft made of composite materials made of carbon fiber and plastic is not only light, but also consumes less power and has low noise; the disk of an electronic computer made of carbon fiber can improve the storage capacity and computing speed of the computer; use carbon ...

Problems solved by technology

[0006] In the above-mentioned applications, if a large-area wiring is required, the method of increasing the voltage and using many connectors in parallel, but this method will have safety concerns, additional costs, heavy weight and poor aesthetics, so it is not suitable for large-scale wiring. Large-area wiring, electric leakage is very easy to occur at the joints, which poses a certain safety threat to users of carbon fiber heating cables
