A methodology is disclosed to produce nanostructured carbon particles that act as effective reinforcements. The process is conducted in the solid state at close to ambient conditions. The carbon nanostructures produced under this discovery are nanostructured and are synthesized by mechanical means at standard conditions. The benefit of this processing methodology is that those carbon nanostructures can be used as effective reinforcements for composites of various matrices. As example, are to demonstrate its effectiveness the following matrices were including in testing: ceramic, metallic, and polymeric (organic and inorganic), as well as bio-polymers. The reinforcements have been introduced in those matrices at room and elevated temperatures. The raw material is carbon soot that is a byproduct and hence abundant and cheaper than pristine carbon alternatives (e.g. nanotubes, graphene).

To provide a porous molding that can be used as a molding that has sufficient strength to be self-supportable even when the dimensions change due to absorbing water and that can be suitably used as a filter for removing impurities in a liquid or gas. A porous molding is achieved by sintering a mixed powder including a dried gel powder and a thermoplastic resin powder, wherein the ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder d.sub.2/d.sub.1 is 1.3 or greater, and the difference ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder and the average particle diameter d.sub.3 of the dried gel powder when absorbing water and swelling is (d.sub.3d.sub.2)/d.sub.1 is 4.0 or less.

A process of producing a composite motor vehicle component, the process comprising the steps of: heating a surface treated steel part (1) to an austenite temperature so as to form austenite in said steel part; forming the steel part to a desired shape, cooling the steel part to a temperature below 500 C., applying a patch (2) of a prepreg fibre reinforced polymer to at least a part of said steel part, pressing the applied patch (2) of fibre reinforced polymer into adhesion to steel part (1), and at least partly curing said patch inside said pressing tool.

Provided is a core-sheath composite fiber which is easily moldable into a composite material or the like and is also excellent in strength. The core-sheath composite fiber comprises a core member containing polyamide and a sheath member containing modified polyethylene, and the core member has a melting point higher by at least 170 C. than a melting point of the sheath member.

Surface micro-texturing has been proven an effective way to reduce friction and wear for tribological applications. There is provided a low cost hot sintering method to apply micro-texturing on an advanced bearing polymer material. First, one face of the mold was micro-textured using a micro-casting method. Second, the cured Aromatic Thermosetting coPolyester (ATSP) powder was filled in the mold. Next, the filled mold was placed in a hot press for a hot sintering process. Finally, the textured bulk ATSP was cooled. The micro-textured ATSP bulk material was machined and compared with plain untextured material. The micro-textured material could effectively reduce friction at speeds lower than 2.46 m/s: 14% reduction in average.

The invention relates to an environmentally friendly fuel made of rubber and a manufacturing method thereof. The manufacturing method comprises the steps of pulverizing a rubber material into rubber powder; and mixing the rubber powder with a toxin elimination material to eliminate deleterious compositions such as chlorine and sulfur, wherein the toxin elimination material comprises a non-halogen flame retardant and a desulfurizing agent.

A method for manufacturing panels with at least a substrate and a top layer. The method having the steps of providing a granulate having thermoplastic material and having an average particle size of less than 1 millimeter, forming a substrate layer by strewing the granulate, consolidating the layer between the belts of a continuous press device, and providing the top layer on the substrate.

Embodiments described herein relate generally to systems and methods for manufacturing a master batch with a graphitic material dispersed in a polymer matrix. In some embodiments, a method for manufacturing the master batch can include combining the graphitic material with a polymer, adding a supercritical fluid to the mixture, and depressurizing the supercritical fluid to remove the supercritical fluid. In some embodiments, the method includes mixing the graphitic material and the polymer for a first time period to form a first mixture and transferring the supercritical fluid to the first mixture to form a second mixture. In some embodiments, the method includes mixing the second mixture for a second time period and depressurizing the second mixture to allow the supercritical fluid to transition to a gas phase.

Provided is a shoe sole having a structure in which a polyhedral hollow cell made of a synthetic resin, configured as a polyhedron, and having an empty space formed therein is bonded with other polyhedral hollow cells by a hot melt adhesive part, wherein the hot melt adhesive part is provided between the multiple polyhedral hollow cells so that no voids are formed therebetween, and a plane structure of the polyhedral hollow cells bonded with each other has a shape of a human sole.

A valve head engageable and disengageable with a valve seat of a valve comprises a valve body that includes a recess, a disk at one axial end of the recess and a flange at the other axial end of the recess so that the recess is positioned axially between a portion of the disk and a portion of the flange. The outermost portion of the flange extends outwardly beyond the outermost portion of the disk. A covering made of a material different from and more elastic than the material forming the valve body entirely covers the disk. A portion of the covering is positioned in the recess to mechanically connect the covering to the valve body. The outermost portion of the flange is in direct contact with the covering.
