Abstract: Disclosed is a method for manufacturing a reinforced synthetic product with a curved geometry, which includes forming a fabric made of at least one filament bundle including a reinforcing fiber material and at least one thermoplastic filament woven with the filament bundle; and combining a heat-formable material with the fabric to form a bendable fabric preform sheet. Also disclosed is a method for manufacturing a reinforced synthetic product with a curved geometry, which includes positioning the bendable fabric preform sheet into a mold with a curved geometry to form a bended fabric preform sheet; and molding the bended fabric preform sheet by heating to form a cured product.

Abstract: A wound dressing for covering a wound includes a textile layer woven by polyacrylonitrile-based activated carbon fiber, and an absorbent layer provided on one side of the textile layer away from the wound. The activated carbon fiber is produced by polyacrylonitrile oxidized fiber in a moisturized carbon dioxide atmosphere at the temperature of 700° C. to 1200° C. for 1 to 60 minutes. The material of the absorbent layer is cotton, alginate, poly vinyl alcohol, or a combination thereof. The water absorbing ability of the absorbent layer is superior to that of the textile layer. Because the textile layer does not produce dust and can keep dry, the hard-to-heal wounds can be prevented.

Abstract: A porous carbonized substrate and its preparation method and uses are provided. The porous carbonized substrate has an oxygen content ranging from about 1 wt % to about 13 wt % and a nitrogen content ranging from about 2 wt % to about 16 wt %, based on the total weight of the substrate. The porous carbonized substrate can be prepared by a method comprising the following steps: providing a fiber substrate containing one or more oxidized fibers, one or more polyamide fibers or a mixture thereof; and thermally treating the fiber substrate under an inert gas atmosphere, wherein the thermally treating step comprises putting the fiber substrate in the inert gas atmosphere and increasing the temperature of the inert gas atmosphere to an elevated temperature ranging from about 700° C. to about 2000° C. with a rate of from about 50° C./minute to about 300° C./minute. The porous carbonized substrate is used as a gas diffusion layer of a fuel cell.

Moreover, the carbonized paper of the subject invention is useful as the anti-electromagnetic material and reinforced composite material.

Abstract: A process for modifying a carbonized substrate and a modified carbonized substrate obtained therefrom are provided. The process involves the application of a mixture containing a hydrophobic polymer and a carbonaceous material onto a carbonized substrate which is not subjected to a hydrophobic treatment. The subject invention uses a simpler procedure to modify a carbonized substrate to provide a modified carbonized substrate with good conductivity, air permeability, and hydrophobicity. The modified carbonized substrate is suitable for use as the material for the gas diffusion layer of the electrode in fuel cells.
