METALLIC CORD, RUBBER/CORD COMPOSITE OBJECT, AND PNEUMATIC TIRE OBTAINED USING THE SAME

Document Type and Number:

WIPO Patent Application WO/2007/063951

Kind Code:

A1

Abstract:

A rubber/cord composite object (9) which comprises: metallic cords (10) comprising plated wires (17E) obtained by forming a brass deposit layer (16) on the surface of uncoated wires (15) and drawing the plated wires; and a rubber (12) bonded to the metallic cords (10) through vulcanization. When the composite object is held in an atmosphere having a temperature of 50-100°C and a humidity of 60-100% for 1 hour to 20 days to bring the brass deposit layer into the state of being deteriorated by moisture and heat, then the deposit crystal grains present in the brass deposit layer (16) have an average grain diameter of 50 nm or smaller and a grain-boundary fractal dimension in the range of 1.001-1.500.
