Abstract:

The report describes the techniques which are used for evaluating some of the important mechanical and physical properties of fibers and yarns. These include density, strength, modulus of elasticity, and repeated flexing properties. The test procedures described are those in use at the time this report was prepared. They have been in use for some time and a considerable amount of data have been generated which has demonstrated the reliability of the methods. These techniques and procedures will be reviewed and updated as required. They are compiled and reported for the purpose of 1 acquainting those concerned with fiber property measurement with those techniques which have been found to be useful for gathering data on a variety of types of fibers and, 2 to provide Air Force contractors and fiber users with the basic techniques used by the Air Force Materials Laboratory in order that valid comparisons of data can be made.
