Abstract
In order to take full advantage of combined effects of metal and plastic materials, we have developed a composite tape combining lead foil which lacks mechanical strength with plastic film which imparts strength. This composite tape is designed to serve the purpose of a water-impervious layer in an XLPE cable. Evaluation of its properties such as corrosion resistance, fatigue, expansion and shrinkage was made. The results of tests indicate that the combination of lead foil with plastic film is more effective in several ways than either alone. As one of its applications, the lead laminate tape was used as water impervious layer in an XLPE cable. This composite materials may be used not only in XLPE cable applications but also in many other various fields of industry.
