Estimating the lifetime of tennis strings

Conclusions

-- The static and dynamic strength characteristics of experimental specimens of tennis string have been studied; these were prepared on a basis of nylon complex yarn with a polyamide coating.

-- It was shown that the experimental strings have a high strength, good fatigue characteristics, in particular high resistance to abrasion, which permits one to increase their lifetime.

-- Play tests of experimental strings in rackets which were performed on open and closed tennis courts have supported an elevated lifetime for these strings as compared with serially produced nylon string, and correspond to the level of foreign analogs.
