Abstract
The present disclosure provides a header for a vehicle upper body structure. The header includes an elongated body extending between a first side and a second side. The elongated body includes a polymer and a plurality of fibers. The elongated body includes a front end and a back end. The front end is configured to be coupled to a windshield. The back end is configured to be coupled to a roof. At least a portion of the elongated body has a transparency of greater than or equal to about 4%.

A header for a vehicle upper body structure comprising:
- an elongated body extending between a first side and a second side, the elongated body comprising a polymer and a plurality of fibers, the elongated body comprising,
- a front end configured to be coupled to a windshield,
- a back end configured to be coupled to a roof,
- a first region including a first outer portion including the first side and a second outer portion including the second side, the first region having a first volume percent of fibers that is greater than or equal to about 10 volume percent, a first transparency and a first tensile strength,
- a second region at least partially disposed between the first outer portion and the second outer portion, the second region having a second volume percent of fibers, a second transparency and a second tensile strength,
- wherein
- the second volume percent of fibers is less than the first volume percent of fibers,
- the second transparency is greater than the first transparency,
- the second tensile strength is less than the first tensile strength, and
- at least a portion of the elongated body has a transparency of greater than or equal to about 4%.
