    Abstract: The invention relates to a reinforcing structure (13), comprising metallic elements (15) (16), to be used to reinforce stiff composite articles (14) comprising such reinforcing structure and a polymer matrix. The reinforcing structure comprises metallic elements with structural deformations in order to improve the bending properties of the reinforcing structure and the impact properties of the stiff composite article, for which the reinforcing structure is used. The metallic elements run essentially parallel to each other.

  • Patent number: 6723425
    Abstract: A thermally conductive molded article is produced by molding a conductive composition into a predetermined shape. The composition includes a polymer matrix and carbon powders. The carbon powders are obtained by graphitizing a polymeric material that has an aromatic ring on its main chain by heating. The carbon powders are aligned in a certain direction in the polymer matrix. Thus, the molded article can be produced easily and effectively that has excellent thermal conductivity in a given direction and that is suitable for use as a heat radiator, heat transfer member, or a component thereof in electronic hardware.

  • Patent number: 6709714
    Abstract: The present invention relates to a method of producing high-density polyidimide (HPI) films and its production equipment. The production equipment comprises a raw material supplying means, a vacuum cavity, an energy supplier, a clad laminator, and a baked solidified polymer. The foregoing components constitutes the production equipment, using the monomer with the CONH bond or copolymer as raw materials to extract the unsaturated C═N bond by heat, electrons, light, radiation rays or ions as energy under low-pressure environment, so that the H in vacuum can extract the non-solidified HPI film from the electronic radical covalent polymers and via heat or light to rearrange the structure into a solidified HPI film. By means of the method according to the present invention, the original HPI that is not easily to produce as a film can be easily made in form of a film of HPI polymer on the clad laminator.

  • Patent number: 6620895
    Abstract: Polyethylenes made from ethylene and a series of &agr;-olefins using a catalyst that copolymerizes ethylene and &agr;-olefins usually have excellent melt processing characteristics, especially in uses where high zero shear viscosity and low high shear viscosity are desirable. These polyethylenes are preferably made by forming the &agr;-olefins in situ from ethylene during the polymerization process. The polyethylenes are especially useful in blow molding, extrusion or extruded blown film processes.

  • Patent number: 6488872
    Abstract: Microfabricated devices and methods of manufacturing the devices are disclosed. The devices are manufactured from a substrate having microscale fluid channels, and polymerizing a polymerizable mixture in the channels to form stimuli-responsive operating components of the device. The operating components can be functional or structural components. The method of manufacture obviates the traditional assembly of microscale components to form a device because the microscale components are formed in situ on or within the device.
