Category Archives: Tensile Strength
Head FXP is a string that seems to be largely overlooked and I am surprised after seeing the results of the installation and testing!
|String Name||Category||Gauge||Ultimate Tensile Strength/Lbs||Knot Strength/Lbs||Country of Origin|
|Head FXP||Multifilament - Nylon||17||165.9||93.4||Japan|
Both the tensile strength and knot strength are exceptional and the graph shows that this string is very “elastic” which is a good thing for tennis racquet string but sometimes just not considered.
The area under the solid red lines is considered a stress-strain curve and indicates the “elasticity” of string by how close the lines fit from 0 to 50 three (3) times. A perfectly elastic material would be one line even though it went through three (3) cycles. What you see here is quite good and one of the reasons it is the winner!
Racquet Quest is going to add a “winner” of the week to our website as a way to develop a fun way to look at string!
Each week we will select a string that has exhibited outstanding properties from one of five (5) major categories:
- Synthetic Gut
- Natural gut
- PEEK Monofilament
- Polyester Monofilament
The winning string must have been installed in the most recent week either in a client or demo racquet.
We will include as much information as possible including graphs and the country of origin.
We will try to post “And the Winner is…” on Friday so take look!
Racquet Quest, LLC has for years been doing the extensive evaluation of racquets and string for the benefit of our client’s customization requirements.
Now we are making this evaluation “program” available to anyone that wants to dig deeper into the workings of the string in the racquet!
This is serious stuff and requires significant resources but it is worth it!
Please contact us of you would like to take advantage of our evaluation program!
