دراسة تأثير الكاؤولين في تصميم عجنه مطاطية لإطارات الطائرات

الملخص EN

This research aims to use the Kaolin material (which is available, cheap, and can undergoes high temperatures) in the design of the rubber master batch which is able to satisfy the special requirements those related with the applications of tires used in land and take off of the airplanes, such as : High Abrasion Resistance, Superior Adhesion between rubber and metals, Suitable Damping Properties, and Resistance to Swelling and High Temperatures.

This research has been carried out by using Hard Air Floated Kaolin with 3 μm particle size (DIXIE CLAY) in the laboratory of Babylon Tires Company, and the properties have been measured according to the standards specifications (ASTM).

The results showed that : the Adhesion Force has improved when adding Kaolin to the master batch of Natural Rubber (NR) from 33 N to 190 N, Abrasion Resistance (by using the weight difference method) has improved from 0.0096 g to 0.0173 g, Rebound Resilience has improved (decreased) from 45 % to 68 % (i.e.

the damping or the hysterises has increased from 55 % to 68 %), and at last Resistances to Swelling and Ageing have been improved greatly.
