Embodiment Construction

[0012] A kind of welding method that realizes carbon fiber and metal provided by the present invention, its process and steps are as follows:

[0013] (1) Slurry: Peel off the carbon fiber precursor skin, and smear the diluted copper paste on the carbon fiber precursor;

[0014] (2) Curing: place the above-mentioned sized carbon fiber precursors in a constant temperature furnace at 130° C. to 150° C. for 25 to 35 minutes;

[0015] (3) Tin coating: apply low-temperature solder to the carbon fiber precursor with a low-temperature soldering iron;

[0016] (4) Welding: quickly weld the carbon fiber precursor and the metal wire with a high-temperature soldering iron;

[0017] (5) Put a heat-shrinkable tube on the welded joint.

Abstract

The invention discloses a method for realizing the welding of carbon fiber with metal, which comprises the following steps: slurry plating: stripping off the outer skin of a carbon fiber original wire head, and plating diluted copper slurry on the carbon fiber original wire head; curing: putting the slurry-plated carbon fiber original wire head in a constant temperature oven with the temperature of 130-150 DEG C for 25-35 minutes; tin plating: plating low-temperature soldering tin on the carbon fiber original wire head by using a low-temperature soldering iron; and welding: fast welding the carbon fiber original wire head with a metal wire by using a high-temperature soldering iron. The welding method provided by the invention enables the connection between the carbon fiber and the metal to be uniform, firm, and safe and reliable.

Description

technical field [0001] The invention relates to a welding method, in particular to a welding method of carbon fiber filaments and metal wires. Background technique [0002] Carbon fiber is a new material with excellent mechanical properties. In the energized state, the molecular activities of carbon fiber oscillate and do Brownian motion to obtain heat. The impact and friction between molecules generate heat and penetrate the medium. The whole heating process is silent, lightless and pollution-free. A large number of experimental data show that the electrothermal conversion rate of carbon fiber materials is as high as 98%, which is nearly 30% higher than that of traditional metal heating elements, and the energy saving advantage is obvious. But in actual use, the carbon fiber wire needs to be connected with the metal wire to connect the circuit, and the connection between the carbon fiber wire and the metal needs to be completed. Since the bundled carbon fiber filaments ar...
