Method of making flexible ceramic fibers and polymer composite
The present application discloses and claims a method to make a flexible ceramic fibers (Flexiramics™) and polymer composites. The resulting composite has an improved mechanical strength (tensile) when compared with the Flexiramics™ respective the nanofibers alone. Additionally a composite has better properties than the polymer alone such as lower fire retardancy, higher thermal conductivity and lower thermal expansion. Several different polymers can be used, both thermosets and thermoplastics. Flexiramics™ has unique physical characteristic and the composite materials can be used for numerous industrial and laboratory applications.
Gas turbine moving blade
A moving blade for a turbine or compressor stage of a gas turbine is provided, including a vane (10) and a radially outer shroud (20), for at least one contour point (P.sub.K) of an outer contour of a profile cross section (P) of the vane at a radial outer gas channel boundary, the wall thickness of the shroud at at least one edge point (P.sub.R) of the shroud, whose connecting line (V), including the contour point with a normal (N), which is perpendicular to the outer contour of the profile cross section in the contour point, encloses an angle (σ), which is no more than 5°, is less than a wall thickness of the shroud at the contour point, the wall thickness of the shroud decreasing strictly monotonously along the connecting line.
Method and device for manufacturing protein fiber
The present invention relates to a method for manufacturing a protein fiber, including an extension and contraction step of contracting or extending a protein raw fiber containing a protein by bringing the protein raw fiber into contact with a liquid or vapor; and a drying step of drying the protein raw fiber that has undergone the extension and contraction step while adjusting a length of the protein raw fiber to an arbitrary length.
Process for producing a non-woven fabric
A process for producing a nonwoven fabric comprising forming a polymer composition comprising a primary polypropylene and at least one secondary polyolefin; in a spunbond process, forming fibers then fabric from the polymer composition; and exposing the fabric to an heating environment within a range from 50° C. to 250° C.
FOCUSED ROTARY JET SPINNING DEVICES AND METHODS OF USE THEREOF
Systems and methods for focused direction deposition of a micron or nanometer dimension polymeric fiber and materials of such fibers are described herein. Systems and methods employ one or more gas flows to entrain and deflect fibers produced by a rotary jet spinning system forming a focused fiber stream. Some embodiments enable control of alignment and distribution of the fibers with a relatively high fiber throughput.
