Notes:
A detailed description of new developments of the flexible thermomechanical analyzer for fibers (FTMA) is presented. The advances consist of a data acquisition system; an improved drive system, with potential for closed loop operation; a single tension transducer for slow and fast changes; reduction of mechanical vibration; use of fast thermocouples. A thorough investigation of the instrument included characterization of the temperature and tension sensing systems, and determination of their detection limits. Comparisons between FTMA performances before and after the introduction of changes clearly illustrate the improvements achieved. The combination of turbulence and inadequate mixing of hot and cold air causes temperature fluctuations, which need to be reduced. Other developments are planned. © 1995 American Institute of Physics.
