    摘要： High tensile carbon fibers are provided with a high yield process in which, after oxidation of a precursor, the fibers are first precarbonized in an inert atmosphere to to about 600.degree. C. while imparting 5-10% stretch. In precarbonizing, the fibers are initially heated in a sweeping manner with substantial volumes of hot inert gas which is extracted along with products of decomposition before the fibers are cooled to a low, non-reactive exit temperature. The arrangement minimizes redeposition of tars on the fibers and stretches the fibers in a range in which substantial off-gassing occurs. Thereafter the fibers are finally carbonized at a higher temperature with a different tension being applied, to provide a more reliable less sensitive process that enables oxidation to be effected more rapidly.

    摘要： Apparatus for removing a fill yarn from a web of warp tows advances the web lengthwise across a tabletop having opposite pairs of bars at the leading edge thereof for separating the outermost tow at each of the opposite edges of the web from the remaining tows within the web. Rotatable cutting wheels which are resiliently urged against the top of a rotating shaft at the underside of the web sever the fill yarn between the outermost tows and the remaining tows of the web to form separate fill yarn lengths extending across the width of the web. As the advancing web is then divided along a central portion thereof, the separate lengths of fill yarn are removed by a hook mounted within a central portion of the tabletop and reciprocating between positions above and below the tabletop so as to hook each separate length of fill yarn and begin pulling it down through the tabletop. As each length of fill yarn is pulled down through the tabletop by the hook, it is engaged by a pair of opposing rollers and pulled into the inside of a hollow duct where an air stream carries the length of fill yarn away for disposal.

    摘要： It is disclosed that the properties of epoxy resins may be improved by incorporating therein at least one metal selected from the group consisting of boron, molybdenum, rhenium, tungsten and zirconium. The selection of a particular metal atom for incorporation into the epoxy resin or a combination of these metals will depend on the specific resin properties desired. The metal containing thermosetting resin is obtained by reacting an epoxy resin and one or more metal compounds selected from the following group:(a) the reaction product of a polyol containing more than two hydroxy groups with boric acid;(b) the reaction product of a polyol containing more than two hydroxy groups and a metal complex which is the reaction product of tungsten carbonyl with pyrrolidine;(c) the reaction product of a polyol containing more than two hydroxy groups and a metal complex which is the reaction product of rhenium carbonyl with pyrrolidine;(d) the reaction product of a polyol containing more than two hydroxy groups and a metal complex which is the reaction product of molybdenum carbonyl with pyrrolidine; and(e) zirconium acetate.

    摘要： Reinforcement fiber for fiber-reinforced resin composites such as graphite tows are spliced by applying a solution of a linear, soluble, high glass transition temperature polyimide having good thermal-oxidative stability to the broken ends of a fiber, placing the ends in contact and removing solvent. The preferred polyimide is an aromatic-cycloaliphatic diamine such as 5,(6)-amino-1-(4' amino phenyl)-1,3-trimethylindane (DAPI) imidized with a dianhydride such as PMDA or BTDA. The soluble polyimide can be preapplied to the fiber as a sizing. The splices are not apparent by visual inspection nor by instrumental scanning of cured composites indicating there is no blistering nor loss of strength.

    摘要： A fibrous carbon material is first coated with a thermosetting material which remains flexible after being subjected to curing temperatures. The thermosetting material contains a refractory metal capable of reacting with boron to form a metal boride. This thermosetting resin is then cured. The fibrous carbon material is then impregnated with a second thermosetting resin containing a boron compound and, optionally, a refractory metal capable of reacting with boron to form a metal boride. The second thermosetting resin is at least partially cured and a plurality of layers of the fibrous material is then assembled to form a laminate. The laminate is heated to a temperature sufficient to carbonize the thermosetting resin. The resultant carbon-carbon composite has better oxidation resistance, improved high temperature stability, higher density and improved interlaminar tensile strength than does a composite prepared without the presence of the refractory metal in the thermosetting resin.
