Abstract
Disclosed are a hybrid fiber cord comprising a nylon filament and an aramid filament, the cord having more uniform physical properties and better strength and fatigue properties and being able to be made more easily than the conventional hybrid fiber cords such that it can be used to make an ultra high performance tire, and a method for manufacturing the same. The hybrid fiber cord comprises a nylon primarily-twisted yarn having a first twist number, and an aramid primarily-twisted yarn having a second twist number. The first twist number is identical with the second twist number. The nylon and aramid primarily-twisted yarns are secondarily-twisted together to have identical structures with each other.
