摘要： A method of making a three-dimensional web is provided. The method comprises spinning continuous filaments from a spinneret, moving the spun continuous filaments along a travel path having an end, and rotating a collection surface at or proximate to the end of the travel path. The collection surface comprises cavities and land areas. The land areas are tangentially planar with an outer surface of the collection surface. The cavities are recessed with respect to the outer surface of the collection surface. The method comprises applying a fluid pressure to the collection surface and collecting the filaments on the collection surface to create an intermediate three-dimensional web having first regions formed in the cavities and second regions formed on the land areas. The first and second regions differ in at least one intensive property. The method comprises bonding the intermediate web using a bonding operation to form a final three-dimensional web.

摘要： A system and method for making a biomaterial device includes a support structure providing a shape for a biomaterial device. At least one applicator has a supply of biomaterial solution and is positioned along the support structure. The at least one applicator forms a biomaterial fiber by applying shear force to the biomaterial solution and delivering the biomaterial fiber to the support structure. A controller causes relative movement between the support structure and the at least one applicator, and the biomaterial fiber is arranged on the support structure according to the relative movement to form the biomaterial device. The biomaterial may be silk fibroin which may be wound onto a reciprocating and rotating mandrel. Control over the properties of the biomaterial device is achieved through appropriate selection of material processing, winding strategy, and post-winding processing.

摘要： Disclosed are methods of forming three dimensional arrays of aligned nanofibers in an open, loose structure of any desired depth. The arrays are formed according to an electrospinning process utilizing two parallel conducting plates to align the fibers and rotating tracks to distribute the fibers throughout the array. Arrays can be used as formed, for instance in tissue engineering applications as three dimensional scaffolding constructs. As-formed arrays can be combined with other materials to form a composite 3-D structure. For instance, composite polymeric materials can be electrospun to form composite nanofibers within the array. Multiple polymeric materials can be electrospun at different areas of the array to form a composite array including materially different nanofibers throughout the array. The arrays can be loaded with other fibrous or non-fibrous materials to form a composite array. Arrays can also be rolled to form a uniaxial fiber bundle.
