Fabrication of composite wire of lead coated on glass fiber by extrusion

A new technology of using lead coated on glass fiber to produce continuous wire for battery of electric vehicles (EVs) and hybrid electric vehicles (HEVs) was studied. Some new devices were made to improve the material capability, and the technological parameters were determined. The relationships among different parameters in the new technology were discussed, especially the relationship between the coating speed and other parameters. The microstructure and tensile strength of the comoosite wire were also analyzed.
