PHENOMENOLOGICAL RESEARCH INTO FAILURE MECHANISMS OF CORD REINFORCED RUBBER SYSTEMS

THE REPORT DESCRIBES THE DEGRADATION OF CORD REINFORCED RUBBER TEST SYSTEMS DURING IDEALIZED 'IN TIRE' STRAIN CYCLING. THIS STRAIN CYCLING WAS A COMPRISE BETWEEN RATE, MAGNITUDE, AND WAVEFORM, SIMULATING ACTUAL IN TIRE BEHAVIOR AND BEING PREDOMINANTLY COMPRESSIVE, THEREBY INDUCING CLASSIC CORD FATIGUE FAILURE. THE ULTIMATE OBJECTIVE WAS TO DESCRIBE THE ORIGIN AND PROPAGATION OF CORD IN RUBBER DEGRADATION FOR TEST SYSTEMS WHICH EXPERIENCED HIGH STRAIN RATE LOADING, STRAIN CYCLES, AND TEMPERATURE ENCOUNTERED IN NORMAL AND ABUSIVE TIRE USE. INHERENT PROPERTY AND GEOMETRICAL CHANGES WERE NOTED AND CHANGES IN FIBER PROPERTIES WERE MEASURED, FROM WHICH CHANGES IN CORD PROPERTIES COULD BE ASSESSED. FIBER TYPES EXAMINED IN CORD FORM WERE NYLON 66, NYLON 6, POLYESTER AND RAYON. /AUTHOR/
