Explain the process of testing the strength of fibres with diagram |
|
Answer» Two types of methods are USED to measure fiber STRENGTH: single filament TESTING and dry bundle or tow testing. Single filament testing is the most direct route to determining fiber strength, and thereby provides the best data for understanding the fundamentals of behavior and variability. On the negative side, this technique is somewhat difficult because handling of small-diameter, high-modulus fibers and measuring small loads and small filament diameters requires special care to avoid errors that can compromise the accuracy of the test. Testing of tows is often used so that these issues can be avoided. Tow testing is ATTRACTIVE in that it allows the evaluation of hundreds or thousands of filaments simultaneously. |
