Abstract

A hybrid structural assembly includes a vehicle structural member extending from a first end to a second end, and a composite reinforcement member attached to the vehicle structural member between the first and second ends of the vehicle structural member. The composite reinforcement member being formed by a continuous method and cut to a predetermined length extending from the first end to the second end.

First claim

The invention claimed is:

1. A hybrid structural assembly comprising:
a vehicle structural member extending from a first end to a second end;
a composite reinforcement member attached to and disposed within the vehicle structural member between the first and second ends of the vehicle structural member, the composite reinforcement member being formed by a continuous method and cut to a predetermined length extending from the first end to the second end; and
a fitting disposed within the vehicle structural member and fixed to the composite reinforcement member, the fitting connecting a first longitudinal end of the composite reinforcement member to one of the vehicle structural member or an adjacent vehicle structural member,
wherein the vehicle structural member is one of a vehicle pillar, a rocker panel, or a body cross-member.

2. The hybrid structural assembly of claim 1 , wherein the composite reinforcement member has a uniform cross-section from a first longitudinal end to a second longitudinal end.

3. The hybrid structural assembly of claim 2 , wherein the cross section of the composite reinforcement member defines a closed shape.

4. The hybrid structural assembly of claim 2 , wherein the cross-section of the composite reinforcement member defines an open shape.

5. The hybrid structural assembly of claim 1 , wherein the composite reinforcement member includes a plurality of fibers.

6. The hybrid structural assembly of claim 5 , wherein the vehicle structural member extends continuously between the first end and the second end, and the at least one of the plurality of fibers extends along the vehicle structural member between the first end and the second end.

7. The hybrid structural assembly of claim 5 , wherein the plurality of fibers extend continuously from a first longitudinal end of the composite reinforcement member to a second longitudinal end of the composite reinforcement member.

8. The hybrid structural assembly of claim 5 , wherein the plurality of fibers are unidirectional.

9. The hybrid structural assembly of claim 1 , wherein a first longitudinal end of the composite reinforcement member and a second longitudinal end of the composite reinforcement member are disposed between the first end of the vehicle structural member and the second end of the vehicle structural member.

10. The hybrid structural assembly of claim 1 , wherein the continuous method is pultrusion.

11. The hybrid structural assembly of claim 10 , wherein the continuous method includes applying an adhesive layer that is an outermost layer of the composite reinforcement member.

12. The hybrid structural assembly of claim 1 , further comprising a second fitting disposed within the vehicle structural member and fixed to the composite reinforcement member, the second fitting connecting a second longitudinal end of the composite reinforcement member to one of the vehicle structural member or an adjacent vehicle structural member.

13. The hybrid structural assembly of claim 1 , wherein the vehicle structural member includes an inner member and an outer member outboard of the inner member, and the composite reinforcement member is disposed between the inner member and the outer member.

14. A vehicle body comprising:
a vehicle structural member including a first end and a second end;
a composite reinforcement member attached to and disposed within the vehicle structural member, the composite reinforcement member including a first longitudinal end, a second longitudinal end, and a plurality of pultruded fibers extending continuously from the first longitudinal end to the second longitudinal end; and
a fitting disposed within the vehicle structural member and fixed to the composite reinforcement member, the fitting connecting the first longitudinal end of the composite reinforcement member to an adjacent vehicle structural member,
wherein the composite reinforcement member has a uniform cross-section from the first longitudinal end to the second longitudinal end,
and wherein the vehicle structural member is one of a vehicle pillar, a rocker panel, or a body cross-member.

15. The vehicle body of claim 14 , wherein the first longitudinal end of the composite reinforcement member and the second longitudinal end of the composite reinforcement member are disposed between the first end of the vehicle structural member and the second end of the vehicle structural member.

16. A method of producing a hybrid structural assembly, the method comprising:
forming, by a continuous method, a composite reinforcement member;
cutting the composite reinforcement member to a predetermined length extending from a first end of a vehicle structural member to a second end of a vehicle structural member; and
attaching the composite reinforcement member to the vehicle structural member between the first and second ends of the vehicle structural member by at least a fitting disposed within the vehicle structural member,
wherein the vehicle structural member is one of a vehicle pillar, a rocker panel, or a body cross-member.

17. The method of claim 16 , further comprising forming the composite reinforcement member with a uniform cross-section from a first longitudinal end to a second longitudinal end.
