Abstract
A panel door for traversing a curved track. The panel door includes front and back faces formed by membranes and a central area between the membranes with a core material. The back face has a plurality of openings having a set width. The openings in the back face align with channels in the central area. The channels have a width that varies along the depth or the depth of the channel extends to the opposite membrane such that a portion of the membrane is exposed by the channel.

A panel door for traversing a track, the panel door having a perimeter comprising a top surface, a bottom surface, a first side surface and a second side surface, the panel door comprising:
- i. a back face formed by a first membrane;
- ii. a front face formed by a second membrane;
- iii. a central area positioned between the first membrane and the second membrane, the central area comprising a core material;
- iv. an opening formed in the back face through the first membrane, the opening having a length extending from the first side surface to the second side surface, the opening having a width (W) perpendicular to the length of the opening;
- v. a channel in the central area, the channel being open to the opening in the back face, the channel having a length extending from the first side surface to the second side surface, the channel having a width (W1) perpendicular to the length of the channel and a depth (D) extending from the opening in the back face inward towards the front face;
- wherein the width (W1) of the channel varies along its depth (D) and/or the depth (D) of the channel extends to the second membrane such that a portion of the second membrane is exposed by the channel.
