A process for producing silicon carbide whiskers by heating a react solid silicon-containing starting material and carbon-containing starting material in a reaction vessel, wherein a molding material, which is prepared by previously molding the silicon-cotaining starting material into a predetermined shape, and a powdery carbon starting material are heated to a predetermined reaction temperature under a hydrogen gas atmosphere. Silicon carbide whiskers which are linear with no bendings, long fiber length, high aspect ratio and low silicon dioxide impurity can be obtained at a high yield of greater than 90% based on silicon vaporized from the silicon-containing starting material.

A straight tubular ferrous blank of a circular section, starting material of the invention is deformed in its section along its whole length and bent to form a fork with two legs or blades, the thus formed tubular fork is set in a sectional forming die of top and bottom molds; the die has a concave corresponding to a protuberant socket and has also at its end an opening into which a mandrel having a recess corresponding to the same protuberant socket is introduced; the tubular fork set in the sectional die is subjected to the oil hydraulic bulge-forming process together with the mandrel simultaneously forced into the opening to bulge-form the socket, and the desired front fork blank of the single unit type is obtained.

Oil hydraulic bulge-forming process for the manufacture of front fork

A process for producing phenolic novolak filaments having improved heat resistance which comprises melt-spinning a fiber-forming phenolic resin and curing the resulting filaments, wherein at least one compound containing at least one group selected from the group consisting of active hydrogen-containing amino, amide, thioamide, ureylene and thioureylene groups and derivatives of these groups is applied to said phenolic resin before, during or after the curing treatment.

Process for producing modified phenolic novolak fibers

A process for producing a flame-resistant and antifusing cured phenolic continuous filament, characterized by melt-spinning a molten resin of an uncured epoxy-modified novolak resin, and then curing the melt-spun filament obtained, and the filament produced by the aforesaid process.

Melt-spun drawn or undrawn flame-resistant and antifusing cured

A process for producing cured phenolic filaments having improved drawability which comprises contacting cured phenolic filaments with a liquid or vapor having a concentration of at least 25 % by weight of a treating reagent selected from the group consisting of an alcohol of from 1 to 6 carbon atoms, acetone and mixture thereof.

Whisker crystalline silicon carbide is prepared by heating a silicon-containing material for example, elemental silicon, silicon oxides, silicon hydroxides, silicon salts and the like with a halogen and carbon-containing material, such as a mixture of hydrocarbon and chlorine-containing material selected from chlorine, hydrogen chloride, tetrachloromethane and phosgene and halogenated hydrocarbon at a temperature of 800.degree.C or higher under a substantial oxygen and nitrogen gas-free condition.

Process of manufacturing whisker crystalline silicon carbide

A process for producing a drawn or undrawn flame-resistant and anti-fusing cured phenolic continuous filament which comprises melt-spining an uncured novolak resin which may contain a fiber-forming thermoplastic synthetic resin and then curing the melt-spun filament with a curing agent in the presence of a catalyst; characterized by pre-curing the melt-spun filament with an aldehyde as a curing agent in the presence of an acid catalyst, and then curing the pre-cured filament with an aldehyde in the presence of a basic catalyst.
