Abstract

A composite material with an insert-molded attachment steel is provided. The composite material includes a plurality of burring apertures, each of which has a flange in one direction on the attachment steel and is inserted between fibers. A resin is then introduced between the fibers in each burring aperture and external to the flange.

First claim

What is claimed is:

1 . A composite material, comprising:
an insert-molded attachment steel; a plurality of fibers disposed between a plurality of burring apertures, each of which has a flange in one direction formed on the attachment steel; and a resin introduced between the fibers in the burring apertures and external to the flange, wherein a shear strength reinforcing portion that reinforces shear strength between the composite material and the attachment steel is formed by the resin.

2 . The composite material of claim 1 , wherein a portion of the shear strength reinforcing portion has a thickness greater than a thickness of the composite material and a height of the flange.

3 . The composite material of claim 1 , wherein the flange is formed in one direction along a circumference of each burring aperture and is formed in a direction perpendicular to a cross section of the attachment steel.

4 . The composite material of claim 1 , wherein the attachment steel has a welded end formed along an exterior tip coupled to the composite material.

5 . The composite material of claim 1 , wherein each burring aperture is formed as a circular aperture.

6 . The composite material of claim 4 , wherein a first welded end is formed at a portion where the attachment steel extends toward a vehicle body component.

7 . The composite material of claim 6 , wherein a second welded end is formed at a portion where the attachment steel extends and is bent.

8 . A method of forming a composite material with an insert-molded attachment steel, comprising:
forming a plurality of burring apertures, each having a flange in one direction on the attachment steel between fibers; introducing a resin between the fibers in the burring apertures and external to the flange; and forming a shear strength reinforcing portion that reinforces shear strength between the composite material and the attachment steel.

9 . The method of claim 8 further comprising:
forming the flange in one direction along a circumference of each burring aperture; and
forming the flange in a direction perpendicular to a cross section of the attachment steel.
