摘要:
A gypsum board comprises a set gypsum layer having a first face and a second face. A fibrous mat is affixed to at least one of the faces. The mat comprises a non-woven web bonded together with a resinous binder. The web comprises a blend of a major portion composed of chopped continuous glass fibers having an average fiber diameter ranging from about 8 to 17 μm and a minor portion composed of fine staple fibers having an average fiber diameter of less than about 5.5 μm, the minor portion comprising about 1-30 percent of the dry weight of the web. The board is exceedingly durable. It has a smooth surface that is readily finished in an aesthetically pleasing way, using paint or other wall covering systems.

Disclosed herein is a fibrous nonwoven composite structure more commonly referred to as a coform structure. Unlike current coform structures, the material of the present invention is more water-dispersible due to the use of a water-degradable reinforcing fiber matrix.

The present invention provides a thermoplastic resin sheet and its molded article for a packaging material which is heated in a microwave oven and for shielding electromagnetic waves. The above-mentioned resin sheet and molded article are characterized by generating heat when irradiated with microwaves. The present invention is directed to an electroconductive thermoplastic resin sheet which is prepared by first superposing an electroconductive nonwoven fabric mainly comprising electroconductive fibers and heat-meltable fibers upon one surface, both the surfaces, or a part or all of the surface of a thermoplastic resin film as a base material layer, further superposing a thermoplastic resin film as a protective layer upon the nonwoven fabric so that they may come in contact with each other, heating and contact-bonding them at a temperature of the melting point or higher of the heat-meltable fibers, and it is also directed to an electroconductive thermoplastic resin-molded article which is prepared by heating the aforesaid electroconductive thermoplastic resin sheet up to a temperature at which the resin sheet softens, setting the resin sheet between a pair of female and male molds the surface of at least one of which comprises a heat- resistant rubber, and then mating both the molds to mold the resin sheet.

Electrospun biodegradable poly(ester-amide) fabric is especially suitable as a scaffold for tissue engineering and to incorporate drug for burn or wound healing treatment to accelerate healing, or to prevent tissue adhesion after surgery.
摘要:
A base material for a wiping sheet on which powder is to be supported, wherein the ratio of the average pore diameter (D) of the surface of the base material while dry as measured by the mercury penetration method to the average particle diameter (d) of the powder, D/d, ranges from 0.03 to 30, and the base material while dry has a bulk softness of from 0.1 to 5 N/30 mm and a thickness of from 0.3 to 5 mm.
摘要:
A novel non-woven fibre web comprising a plurality of first fibres orientated in the x-, y-, and optionally z-directions, said first fibres being bonded with a polymeric substance, characterised in that one or more continuous strands are embedded within the sub-surface layer of the non-woven fibre web, each continuous strand comprising a plurality of second carbon fibres, is disclosed. A gas diffusion substrate, electrode and membrane electrode assembly comprising said web is also disclosed, all of which may have application in electrochemical devices, for example in a fuel cell.

摘要:
A hybrid prepreg (1) comprises foreign fibers (6) arranged within a prepreg (4), wherein carbon fibers (2) are used as reinforcing fibers. The foreign fibers (6) are arranged at fixed intervals and are in the same direction as the reinforcing fibers (2). The foreign fibers (6) have diameters in the range of 50 - 500 um and the carbon fibers (2) have diameters in the range of 5 - 30 µm. The prepreg (1) can be made by sandwiching the foreign fibers between two sheets of the carbon-fiber-reinforced prepreg (4) and forming the sandwich into an integrated whole. The prepreg can be used for instance for making golf club shafts, fishing rods and racket frames e.g. for tennis.
