Thus, the present invention is applicable to products such as sleeping bags, duvets, snow suits, snow boots and the like. It also has sound and heat proof properties as well as better thermal insulation.

Abstract: In a method of manufacturing an object, a filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The reinforcement portion of the partially molten filament remains in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

Abstract: Composite materials are provided that include nanostructures bound together by a binder material in a manner that provides the composite material with high strain capability and toughness. The nanostructures and binder material form a matrix material in which long fiber reinforcements may be embedded to form a structural composite material. The nanostructures may have relatively low aspect ratios, preventing entanglement during processing. The nanostructures can be arranged in an interconnected network to form a high free-volume skeletal structure within the matrix material that allows the nanostructures to flex and return to their original shapes. As applied to ceramic matrix composite (CMC) materials, this tough, flexible matrix material allows for full bonding of the matrix material with the fiber reinforcements so that CMC materials can realize the full potential of the reinforcing fibers and possess superior inter-laminar strength.
