What happens to a string if it gets scuffed or slightly damaged in terms of properties?

We know the string will not go in the clients’ racquet, but how bad is it, really?

The chart below shows exactly what happens to each string until both fail. We can see precisely how the scuffing affects the string. Both strings behave nearly the same through the three (3) cycles to 50 pounds. We then see that the scuffed string gives up a little earlier than the clean string by about 15%.

So, what’s the Difference?

However, the failure force for both of these strings is very high! Only a handful of strings we have tested exhibit this tensile strength.

So we know this string would never be used in a client racquet, but you could certainly use it for some “experimentation!” And, of course, depending on how many and where the  “rough” spots are you can cut that portion away!
