A COMPARATIVE STUDY OF THE STRENGTH AND THE MICROSCOPIC PROPERTIES OF POLYETHYLENTEREPHTHALATE АND POLYIMID FILMS
The result of the research was to determine the influence of metallizer the mechanical strength polyethyleneterephthalate and polyimide films of varying thickness. The mechanical strength of the films was studied by dynamic loading. The changes of metal cover under tensile stress were also carried out by microscopic research.
