ARAMID TIRE CORD AND MANUFACTURING METHOD THEREOF, CAPABLE OF IMPLEMENTING GOOD TRAVEL PERFORMANCE IN HIGH SPEED TRAVELING

摘要

PURPOSE: Aramid tire cord and a manufacturing method thereof are provided to prevent degradation of material property, and to offer good fatigue resistance at high temperature.;CONSTITUTION: Aramid tire cord includes aramid multifilament(1). The initial modulus change rate is 5% or less after tension repetition experiments with the load of 10% based on the breaking strength in 120°C. The initial modulus change rate (%) = [(M1-M2) / M1×100. M1 is the initial modulus(g/d) before the tension repeated experiment. M2 is the initial modulus(g/d) after the tension repeated experiment.;COPYRIGHT KIPO 2010
