Tensile Strength: The property of a material to resist a stress which tends to pull molecules apart.
At the Tg the tensile strength, chemical resistance, and hardness are significantly reduced while the flexibility is increased. As you might imagine, we do not want our completed airplane to reach the Tg temperature.
This is done because the drawing cold works the material and raises the tensile strength of the material, which these days is usually Type 316 stainless steel.
The objection to manila rope is that it shrinks when wet, is subject to mildew and rot, and has considerably less tensile strength than either nylon or dacron. Securing aircraft. Tie only at the tiedown rings provided for that purpose.
Preliminary results of salt spray tests (24 weeks of exposure) show changes in tensile strength and elongation of Alclad 17ST, when any occurred, to be so small as to be well within the limits of experimental error." ...
