5.5 Effect of temperature on strength and modulus<br />

The relative strength of ZYLON ® decreases from room temperature to 500°C. ZYLON ®<br />

retains 40% of the room temperature strength even at 500°C.<br />

The temperature dependence of modulus is shown below. Even at 400°C, ZYLON ®<br />

retained 75% of modulus at room temperature.<br />

5.6 Hot air shrinkage<br />

Shrinkage (permanent) after hot air treatment for 30 minutes without load was measured.<br />

ZYLON ® shows very low shrinkage as compared with other super fibers.<br />
