Abstract
PURPOSE: To improve the high-speed durability and rolling resistance by a method wherein a compound consisting of rubber, carbon black, sulphur and micro organic short fibre is used as bead filler rubber.
CONSTITUTION: The compound consisting of 40W100 parts of carbon black, 3W15 parts of sulphur and 3W30 parts of micro organic short fibre to 100 parts of rubber such as natural rubber or the like by weight, is used as the bead filler rubber. The property of micro organic short fibre is as follows: the transition temperature of amorphous part to glass is 30°C or below or 120°C or above; the melting point of crystalline part is 160°C or above; the mean length of short fibres is 0.8W30 micrometers; the mean diameter of short fibres is 0.02W0.8 micrometers; and the ratio of length to diameter is 8W400. For example, poly-vinyliden chloride, poly-vinyliden fluoride, poly-p-tert-butyl styrene or the like is used.
