Fibrous monolith processing techniques to fabricate multifunctional structures capable of performing more than one discrete function such as structures capable of bearing structural loads and mechanical stresses in service and also capable of performing at least one additional non-structural function.

Multi-functional composite structures

Fibrous monolith composites having architectures that provide increased flaw insensitivity, improved hardness, wear resistance and damage tolerance and methods of manufacture thereof are provided for use in dynamic environments to mitigate impact damage and increase wear resistance.

Aligned composite structures for mitigation of impact damage and resistance to wear in dynamic environments

Formation of polymeric prototype elements is effected by high pressure and high temperature extrusion of selected materials onto a plate as a ribbon of liquefied polymer comprising poly(2-ethyl-2-oxazoline) and a polar polymer discharged in a programmed pattern.

Water soluble rapid prototyping support and mold material

Formation of polymeric prototype elements is effected by high pressure and high temperature extrusion of selected materials onto a plate as a ribbon of liquefied polymer comprising poly(2-ethyl-2-oxazoline) and a polar polymer is discharged in a programmed pattern.

A water-soluble thermoplastic composition for three-dimensional modeling comprising poly(2-ethyl-2-oxazoline) is disclosed. The composition in the form of an extrudable object may be extruded by an extrusion apparatus in a programmed pattern onto a base as a ribbon of liquified polymer to create a support structure for a prototype object or to create a water-soluble polymeric element.

A ceramic or metal feedstock composition useful for manufacture of prototype elements using a filament or ribbon deposition apparatus, includes a ceramic or metal powder, a binder of ethylene/acrylate copolymer or homopolymer, a wax and liquid plasticizer mixed together in the form of a ribbon or rod which may then be used in a prototyping device.

Ceramic feedstock composition for the manufacture of prototype elements

A carrier is comprised of a thermoplastic polymer such as polyetheretherketone which is formed or fabricated as a uniform thickness, double sided flat sheet of material with wafer passages therethrough and gear teeth formed or fabricated around the peripheral edge thereof so as to be cooperative with a wafer polishing machine. An extrusion or rolling or calendering process provides a flat carrier which is, optionally, coated with thermoset polymer or thermoplastic film.
