Abstract

Methods and devices for manufacturing paneled structures are provided. The methods include manufacturing a frame structure by additive manufacturing methods and scanning a surface of the frame structure to determine whether there is more than a nominal surface deviation at a location where a panel will be disposed. When there is more than a nominal surface deviation, the methods also include generating a panel to be disposed at the location of the frame structure, wherein the panel has an engagement surface that is complimentary to the surface deviation.

First claim

What is claimed is:

1. A method for manufacturing a paneled structure, the method comprising:
scanning an outer surface of a space frame structure to create a three dimensional map of the outer surface corresponding to a first region where a vehicle body panel will be disposed and identifying a surface deviation in the first region from the three dimensional map;
generating the vehicle body panel via additive manufacturing to be disposed along the first region of the outer surface of the space frame structure based on the three dimensional map, wherein the vehicle body panel comprises an engagement feature that is complementary to the surface deviation in the first region of the outer surface of the space frame structure; and
assembling the vehicle body panel to the first region of the outer surface of the space frame structure to form the paneled structure, in which the engagement feature of the vehicle body panel conformingly contacts the surface deviation.

2. The method according to claim 1 , further comprising applying a reinforcing material to the space frame structure having the outer surface by additive manufacturing before the scanning.

3. The method according to claim 1 , further comprising coating the space frame structure with a reinforcing material prior to the scanning.

4. The method according to claim 3 , wherein the coating of the space frame structure with a reinforcing material comprises coating the space frame structure with fibers selected from the group consisting of carbon fibers, glass fibers, aramid fibers, boron fibers, ceramic fibers, polyester fibers, ultra-high molecular weight polyethylene (UHMWPE) fibers, and combinations thereof.

5. The method according to claim 4 , wherein the coating of the space frame structure with fibers comprises aligning the fibers in a predetermined orientation.

6. The method according to claim 3 , further comprising curing or solidifying the reinforcing material under pressure, wherein the pressure is associated with local vacuum bagging, hydro-static pressure, a pneumatically pressurized sleeve, or an autoclave.

7. The method according to claim 1 , further comprising coating a surface of the vehicle body panel with a reinforcing material.

8. The method according to claim 1 , wherein generating the vehicle body panel comprises:
generating an inner surface of the vehicle body panel;
laying the inner surface on a plurality of pins that are arranged and adjusted to the shape of the inner surface;
applying a reinforcing material to the inner surface; and
subjecting the inner surface and reinforcing material to pressure while the inner surface with the reinforcing material is supported by the plurality of pins.

9. A method for manufacturing a paneled structure, the method comprising:
scanning an outer surface of a space frame structure;
comparing a first region of the scanned outer surface of the space frame structure to a second region of a complementary vehicle body panel and determining that the outer surface of the space frame structure has a surface deviation at a location where the first region and the second region will be joined;
generating a corrective component to be disposed at the location, wherein the corrective component comprises an engagement surface that is complimentary to the first region and the second region;
coupling the corrective component to the complementary vehicle body panel to form a corrected complementary vehicle body panel having a corrected engagement surface at the second region;
coating an entirety of the corrected complementary vehicle body panel with a reinforcing material; and
coupling the corrected complementary vehicle body panel to the space frame structure, such that the corrected engagement surface of the corrected complementary panel conformingly contacts and engages with the deviation at the first region of the outer surface of the space frame structure at the location.

10. The method according to claim 9 , wherein at least one of the space frame structure and the complementary vehicle body panel is generated by additive manufacturing.

11. The method according to claim 10 , wherein the space frame structure and the corrected complementary vehicle body panel are coated with reinforcing fibers selected from the group consisting of carbon fibers, glass fibers, aramid fibers, boron fibers, ceramic fibers, polyester fibers, ultra-high molecular weight polyethylene (UHMWPE) fibers, and combinations thereof.

12. The method according to claim 11 , wherein the reinforcing fibers are embedded within a resin matrix.

13. The method according to claim 9 , wherein the generating of the corrective component comprises generating a wedge by additive manufacturing, wherein the wedge conformingly contacts and engages with the first region and the second region.

14. The method according to claim 1 , wherein the generating the vehicle body panel via additive manufacturing comprises generating the vehicle body panel via 3-dimensional printing.
