Abstract: The present disclosure provides an apparatus and method for modifying the shape of a hollow structure. The method may comprise steps of providing a hollow structure having a cross-section with first and second diameters defining a first aspect ratio; heating at least a part of the hollow structure to at least its glass transition temperature, forming a malleable hollow structure; maintaining a positive pressure inside the malleable hollow structure to form a pressurized hollow structure; and pressing against a first side and an opposed second side of a heated part of the pressurized hollow structure, forming a hollow tabular structure having first and second opposed generally flat faces and a second aspect ratio greater than the first aspect ratio.

Abstract: A method for bending a sheet of material into a shaped article includes providing the sheet of material. A reformable area and a non-reformable area of the sheet of material are heated to a first temperature range corresponding to a first viscosity range. The reformable area of the sheet of material is subsequently heated to a second temperature range corresponding to a second viscosity range. The reformable area of the sheet of material is reformed into a selected shape by at least one of sagging the reformable area of the sheet of material and applying a force to the sheet of material outside of or near a boundary of the reformable area.
