Abstract
The present invention relates to a hybrid cowl cross bar manufactured through an improved method of performing an insert injection molding without applying hydraulic pressure to the inside of a metal pipe during injection molding in order to simplify a manufacturing process of a hybrid cowl cross bar and to secure rigidity of the cowl cross bar. According to an aspect of the present invention, a reinforcing material is inserted into a metal pipe that is a material of a cowl cross bar. The metal pipe may be made of a material such as aluminum, magnesium, or steel, like a conventional cowl cross bar. The reinforcing material may be manufactured by extruding a synthetic resin or a composite material (for example, PP+GF50%). A rib may be formed inside the reinforcing material to increase a capability to resist injection pressure when the metal pipe is insert-injected and to secure rigidity.
