摘要： A filament web type precursor fabric for an activated carbon fiber fabric is produced by (i) spreading precursor filaments for preparing activated carbon fiber in a web state; and (ii) punching the precursor filaments for preparing activated carbon fiber spread in a web state to entangle the precursor filaments for preparing activated carbon fiber with each other. The filament web type precursor fabric has a structure in which the precursor filaments for preparing activated carbon fiber are spread in a web form and entangled with each other, and has a weight per unit area ranging from 50 to 500 g/m2. An activated carbon fiber fabric manufactured by activating the filament web type precursor fabric contains yarns with improved and uniform durability and crystallinity, and an shows improved performance of forming microfine pores having a diameter of 1 to 2 nm.

摘要： In the present invention, a water-based wetting dispersant having an acid value of 5 mg KOH/g or more and an amine value of 10 mg KOH/g or less is used to dilute and disperse black carbon and a hydrophobic fluorine resin in an organic solvent to manufacture a slurry for microporous layer formation. In this regard, the added amount of the water-based wetting dispersant is adjusted to 5 to 30 parts by weight on the basis of 100 parts by weight of black carbon. In the present invention, the slurry is applied to at least one surface of carbon fiber paper and dried to form a microporous layer in which two independent peaks appear as analyzed on a particle size graph, followed by compression and deposition thereof to fabricate a gas diffusion layer including the microporous layer in which two independent peaks appear as analyzed on a particle size graph. With the appearance of two independent peaks on a particle size analysis graph, the gas diffusion layer of the present invention has an excellent drainage function, thereby increasing in the current value of the concentration polarization curve at the equivalent voltage value.

摘要： A method for preparing a high quality thermoplastic prepreg, includes: laminating a thermoplastic resin film having a crystallization degree in a range of 1 to 20% on at least one surface of a matrix fiber; and heating the laminate to a higher temperature than a melting point of the film, then, pressing the same. The method uniformly impregnates a matrix fiber with a thermoplastic resin, has a short curing cycle in the formation, and involves no random modification in alignment of fibers in the matrix fiber due to a low crystallization degree of the impregnated thermoplastic resin, thereby increasing rigidity of a formed product and enabling reduction of thickness. Thus produced prepreg has a low weight variation per unit area.

摘要： A laminate for forming a composite material is provided. The laminate has a structure in that unidirectional yarn sheets S in which yarns are arranged in parallel to each other in one direction without bending and thermoplastic resin films F are alternately stacked so that the film F is located between the unidirectional yarn sheets S. The yarn sheets S and the films F having a degree of crystallinity XC of 30% or less are integrally coupled by stitching yarn Y, and adjacent unidirectional yarn sheets S are obliquely stacked at an angle of ±1° to ±90° to a direction in which yarns included in the respective unidirectional yarn sheets S are arranged. The use of unidirectional yarn sheets S, instead of fabrics or multi-axial fabrics, achieves excellent smoothness. Composite material manufactured using the laminate has uniform physical properties such as strength.

摘要： Disclosed is a method for producing roll-type gas diffusion layer. The method includes steps of preparing a carbon paper by using carbon fiber chops having a low modulus of 10 to 100 Gpa; impregnating the prepared carbon paper with a phenol resin or the like, and then carbonizing the same at 1,800 to 2,400° C.; forming a microporous polytetrafluoroethylene resin layer on one of both sides of the carbonized carbon paper, thus to prepare a sheet-like gas diffusion layer; and then, winding the prepared sheet-like gas diffusion layer on a roll.

摘要： A 0° unidirectional yarn prepreg and a preparation method are disclosed. The 0° unidirectional yarn prepreg has high-strength filaments which are arranged in parallel to each other in an axial direction X of a winding roller around which unidirectional yarn prepregs are wound and a resin is impregnated. The method includes steps of: (i) weaving a fabric using a thermoplastic film tape as a warp and using high-strength filaments as wefts; and (ii) performing thermal compression on the woven fabric at a temperature in which the warp is melted. Also, a multiaxial prepreg composite material is prepared by simultaneously and continuously supplying the 0° unidirectional yarn prepreg A prepared as described above method and a 90° unidirectional yarn prepreg B prepared by a conventional warping method to a thermal compression roller, and performing thermal compression thereon.

摘要： An intermediate material of a thermoplastic prepreg for a fuel cell separation plate comprises a hydrophobic thermoplastic resin film and a fiber base. The hydrophobic thermoplastic resin film has a degree of crystallization of 1 to 20%, a thickness of 3 to 50 μm, and (iii) a content of an electroconductive material of 1 to 20 wt. %. The film is laminated on at least one surface of the fiber base. The thermoplastic prepreg for a fuel cell separation plate is manufactured by pressurizing the thermoplastic prepreg intermediate material at a temperature higher than the melting point of the hydrophobic thermoplastic resin film. A fuel cell separation membrane manufactured using the thermoplastic prepreg intermediate material and thermoplastic prepreg is thin and light-weight, and have a good durability.
