In an embodiment, a side door for a vehicle can comprise: a structure comprising a plastic inner shell comprising a fiber strip, and a plastic outer shell comprising an outer shell support beam positioned across a width of the outer shell. The outer shell support beam can comprise a fiber strip with ≧50 wt. % fibers oriented at an angle of less than or equal to ±45° to a main axis. In an embodiment, a method for making the side door for a vehicle can comprise: flow molding a fiber-reinforced polymer over a fiber strip to form a plastic inner shell; flow molding a fiber-reinforced polymer over a fiber strip deposited to form a plastic outer shell, wherein the outer shell comprises an outer shell support beam positioned across a width of the outer shell; and joining the inner shell and the outer shell together to form a composite structure.

1. A side door for a vehicle, comprising: a structure comprising a plastic inner shell comprising an inner shell fiber strip having greater than or equal to 50 wt.% fibers, based upon the total weight of the fibers in the strip, oriented in a direction with an angle of +45° to -45° to a main axis of
1. A side door for a vehicle, comprising: a structure comprising a plastic inner shell comprising an inner shell fiber strip having greater than or equal to 50 wt.% fibers, based upon the total weight of the fibers in the strip, oriented in a direction with an angle of +45° to -45° to a main axis of the inner shell fiber strip, wherein the plastic inner shell comprises at least one of an inner shell support beam, an inner shell window frame, and an inner shell main body, that comprises the inner shell fiber strip; anda plastic outer shell comprising an outer shell support beam positioned across a width of the outer shell, wherein the outer shell support beam comprise an outer shell fiber strip having greater than or equal to 50 wt.% fibers based upon the total weight of the fibers in the strip, oriented in a direction with an angle of +45° to -45° to a main axis of the outer shell fiber strip; andwherein the side door has a score of at least 4 points in a side impact test conducted according to European New Car Assessment Protocol (Euro NCAP) Side Impact Testing Protocol Version 5.2 (November 2011). 2. The side door of claim 1, wherein the plastic inner shell comprises an inner shell support beam positioned across a main body portion of the inner shell, wherein the inner shell support beam comprises substantially unidirectional fiber strip sections. 3. The side door of claim 1, wherein the plastic outer shell comprises at least two non-intersecting outer shell support beams positioned across a width of the outer shell. 4. The side door of claim 1, wherein a window frame portion of the inner shell comprises substantially unidirectional fiber strips positioned across one or more of an upper, a lower, a rear, and a front portion of the window frame portion. 5. The side door of claim 1, wherein a window frame portion of the outer shell comprises substantially unidirectional fiber strip positioned across one or more of an upper, a lower, a rear, and a front portion of the window frame portion. 6. The side door of claim 1, wherein the outer shell support beam substantially unidirectional fiber strip is overmolded with fiber-reinforced polymer material. 7. The side door of claim 1, wherein the inner shell further comprises ribbing positioned in a main body portion. 8. The side door of claim 7, wherein the ribbing is positioned along the rear, bottom, and front periphery of the main body portion. 9. The side door of claim 1, wherein the side door is free of metal structural support elements. 10. The side door of claim 1, wherein the side door has a score of greater than or equal to 6 points in a side impact test as measured according to Euro NCAP Side Impact Testing Protocol Version 5.2 (November 2011). 11. The side door of claim 1, further comprising a hinge integrated to the door, wherein the hinge breaks during the side impact test that results in a door intrusion of greater than 100 mm. 12. The side door of claim 1, wherein the side door has a score of at least 4 in a pole impact test as measured according to Euro NCAP Pole Impact Testing Protocol Version 5.2 (November 2011). 13. A vehicle, comprising: a structural body; anda side door comprising a plastic inner shell comprising at least one of an inner shell support beam, an inner shell window frame, and an inner shell main body, that comprises a substantially unidirectional fiber strip;a plastic outer shell comprising an outer shell support beam positioned across a width of the outer shell, wherein the outer shell support beam comprises a substantially unidirectional fiber strip;a door skin over the plastic outer shell;a window; anda hinge;wherein the side door has a score of at least 4 points in a side impact test conducted according to Euro NCAP Side Impact Testing Protocol Version 5.2 (November 2011) and wherein the hinge breaks during the side impact test. 14. The vehicle of claim 13, wherein the plastic inner shell further comprises an inner shell support beam positioned across a main body portion of the inner shell, wherein the inner shell support beam comprises ribs and the substantially unidirectional fiber strip. 15. The vehicle of claim 13, wherein the plastic outer shell comprises at least two non-intersecting outer shell support beams positioned across a width of the outer shell. 16. The vehicle of claim 13, wherein the side door is free of metal structural support elements. 17. The vehicle of claim 13, wherein the outer shell support beam substantially unidirectional fiber strip is overmolded with fiber-reinforced polymer material. 18. The vehicle of claim 13, wherein the inner shell further comprises ribbing positioned along the rear, bottom, and front of an inner shell main body portion.
