Transparent vehicle A-pillar

1. A motor vehicle frame having an improved field of view, the motor vehicle frame comprising:

a pillar body having an opening positioned between opposite sidewalls of the pillar body;

a transparent material disposed within the opening, the transparent material comprising a transmission coefficient of at least 50 percent for light in the infrared (IR), visible, and ultraviolet (UV) wavelengths and a refractive index between 1 and 2 for visible light; and

resistance wiring embedded within the transparent material, the resistance wiring configured to adjust a temperature of the transparent material to achieve a targeted transparency.

2. The motor vehicle frame of claim 1 , wherein the transparent material comprises an optically transparent polycarbonate.

3. The motor vehicle frame of claim 1 , wherein the transparent material comprises polymethylmethacralate (PMMA).

4. The motor vehicle frame of claim 1 , wherein the transparent material is impregnated into the opening using injection molding.

5. The motor vehicle frame of claim 1 , wherein the pillar is an A-pillar of the motor vehicle.

6. The motor vehicle frame of claim 1 , wherein the opening comprises an elliptical opening centered within the A-pillar.

7. The motor vehicle frame of claim 1 , wherein the resistance wiring comprises a watt density of at least 0.5 watts per square inch.

8. The motor vehicle frame of claim 1 further comprising electrical wiring embedded within the pillar body, the electrical wiring providing electrical continuity across the pillar body.

9. The motor vehicle frame of claim 1 , wherein the opening comprises a width of about 40 mm to about 80 mm.

10. The motor vehicle frame of claim 1 , wherein the opening comprises a length of about 200 mm to about 400 mm.

11. The motor vehicle frame of claim 1 , wherein the pillar body comprises a sidewall width around the opening of less than about 75 mm.

12. The motor vehicle frame of claim 1 , wherein the pillar body further comprises one or more additional openings vertically or horizontally stacked with the opening.

13. A method for providing a motor vehicle frame having an improved field of view, the method comprising:

providing a pillar body having an opening positioned between opposite sidewalls of the pillar body;

filling the opening with a transparent material, the transparent material comprising a transmission coefficient of at least 50 percent for light in the infrared (IR), visible, and ultraviolet (UV) wavelengths and a refractive index between 1 and 2 for visible light; and

embedding resistance wiring within the transparent material, the resistance wiring configured to adjust a temperature of the transparent material to achieve a targeted transparency.

14. The method of claim 13 , wherein filling the opening with a transparent material comprises injecting the transparent material into the opening at a temperature of about 90 to about 150 degrees Celsius and a pressure of about 1 bar to about 200 bars.

15. The method of claim 13 wherein the resistance wiring comprises a watt density of at least 0.5 watts per square inch.

16. A method for reinforcing a motor vehicle frame having an improved field of view, the method comprising:

determining a width and a length of an opening in a pillar of the motor vehicle frame;

determining, based on the width and the length of the opening, principal stresses for the pillar; and

providing a pillar body having the opening positioned between opposite sidewalls of the pillar body, the pillar body comprising reinforcing fibers arranged into fiber tows contoured around the opening, the fiber tows oriented along the principal stresses, the fiber tows comprising a first fiber tow and a second fiber tow, wherein the first fiber tow is contoured around and in direct contact with a perimeter of the opening, and wherein the second fiber tow is contoured around the second fiber tow.

17. The method of claim 16 , wherein the reinforcing fibers comprise glass fibers, carbon fibers, or a combination thereof.

18. The method of claim 16 , wherein providing the pillar body comprises forming an epoxy resin over the fiber tows.

19. The method of claim 16 further comprising filling the opening with a transparent material, the transparent material comprising a transmission coefficient of at least 50 percent for light in the infrared (IR), visible, and ultraviolet (UV) wavelengths and a refractive index between 1 and 2 for visible light.
