A layered composite assembly may include a plurality of composite fiber layers stacked onto one another. Each of the plurality of composite fiber layers may include a main body including a plurality of composite fibers. The main body may be pre-impregnated with at least one resin. Each composite fiber layer also includes a plurality of layer-securing pins secured to the main body. The layer-securing pins are configured to mechanically connect the main body to an adjacent composite fiber layer.

A display device includes a first shape-memory wire that memorizes an extended state and a second shape-memory wire that memorizes a bending state. The laminated layers include a first flexible layer, a second flexible layer, and a display element layer on which light emitting elements are disposed. The first flexible layer includes a first interface between the first flexible layer and a layer in contact with an upper side or a lower side of the first flexible layer. The second flexible layer includes a second interface between the second flexible layer and a layer in contact with an upper side or a lower side of the second flexible layer. The first shape-memory wire is disposed within the first flexible layer or on the first interface. The second shape-memory wire is disposed within the second flexible layer or on the second interface.

A resistively heated shape memory polymer device is made by providing a rod, sheet or substrate that includes a resistive medium. The rod, sheet or substrate is coated with a first shape memory polymer providing a coated intermediate unit. The coated intermediate unit is in turn coated with a conductive material providing a second intermediate unit. The second coated intermediate unit is in turn coated with an outer shape memory polymer. The rod, sheet or substrate is exposed and an electrical lead is attached to the rod, sheet or substrate. The conductive material is exposed and an electrical lead is attached to the conductive material.

A reusable surgical implement is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable rigid, and optionally flexible material to enable the implant to conform to the desired use for the implement in a surgical procedure. The material forming the enclosure is also stretchable and flexible to accommodate the configuration and/or any flexing of the core, and is biologically inert to enable the implant to be sterilized after use for use in subsequent surgical procedures while protecting the material forming the core. The enclosure can be molded around the core in separate portions or components using multiple molding steps to form an enclosure with the desired attributes.
