The present invention relates to a hybrid inner core assembly of a honeycomb structure and a method for manufacturing the same. The hybrid inner core assembly comprises: a steel plate which can be mounted in a vehicle body; a steel core having the steel plate inserted thereinto so that both ends of the longitudinal direction protrude; and a plastic core whose inside is formed in a honeycomb shape, and in which the steel core is inserted into a central axis of the longitudinal direction. An inner pipe included in a trailing arm bush is manufactured into a hybrid form combining steel and plastic through the injection process rather than steel forging process, thereby having reduced weight as compared to a conventional inner pipe manufactured through the steel forging process. |
