An expandable sheath is disclosed herein, which has a first polymeric layer and a braided layer positioned radially outward of the first polymeric layer. The braided layer includes a plurality of filaments braided together. The expandable sheaths further include a resilient elastic layer positioned radially outward of the braided layer. The elastic layer is configured to apply radial force to the braided layer and the first polymeric layer. The expandable sheath further includes a second polymeric layer positioned radially outward of the elastic layer and bonded to the first polymeric layer such that the braided layer and the elastic layer are encapsulated between the first and second polymeric layers. Methods of making and using the devices disclosed herein are also disclosed, as are crimping devices that may be used in methods of making the devices disclosed herein.

A system for constructing a composite structure includes a braiding machine, a winding tool and a forming machine. The composite structure is constructed of a wound tubular braiding. The wound tubular braiding is constructed of a biaxial or triaxial tubular braid of unidirectional tape.

Disclosed herein are abrasion resistant flexible hoses and methods for manufacturing such hose. The abrasion resistant elastomeric hose comprises an inner surface and an outer surface, and a abrasion resistant material embedded in the hose at a depth that imparts a three-dimensional pattern at the outer surface of the hose.

A hose extrusion mandrel for manufacturing rubber hoses includes: a solid thermoplastic, elongate core; and a rubber compound outer layer covering a surface of the elongate core. A ratio between a diameter of the core and a thickness of the rubber compound layer may be between 8 and 11.

A method for fabricating aircraft engine external target parts including complex geometries utilizes reusable reconfigurable shape memory polymer and conformable woven braided carbon fiber sleeves. The method includes providing a tubular three-dimensional reusable shape memory polymer mandrel assembly designed for a target part, and heating the shape memory polymer mandrel.
