A fiber composite assembly and a process of fabricating a fiber composite assembly are disclosed. The fiber composite assembly includes a first composite layer having a first fiber and a second composite layer having a second layer. The first fiber includes a helical portion and the second fiber extends to within the helical portion of the first fiber. A process of fabricating a fiber composite assembly includes elongating a wound fiber preform to form a helical fiber or positioning the first fiber in the first composite layer and positioning the second fiber in the second composite layer.
