摘要： A multi-dimensional (e.g., 3D braided) preform formed of reinforcement strands or filaments is rigidized by impregnating the preform with a resin solution (e.g., silicone resin solution), curing the resin to impart a selected shape to the preform and then heating the shaped preform to convert the cured resin to inorganic solids (e.g., silica solids) so dispersed in an effective amount between the strands as to rigidize the preform. The rigidized preform is then infiltrated with an inorganic matrix (e.g., a ceramic material) to form a composite article.

摘要： An annular fluid seal is provided between a pair of spaced apart machine components, such as a rotor and a stator. The rotatable component includes an annular sealing surface of increasing diameter in a given direction (e.g., along its length or along a radially extending shoulder). An annular fibrous sealing element is disposed proximate the clearance space between the components in such a manner that a sealing portion thereof engaging the other component moves in the direction of increasing diameter as the sealing portion may wear so as to maintain sealing contact with the annular sealing surface. A fluid seal is thereby maintained between the components.

摘要： The apparatus includes a plurality of fiber strand carrier members that are movable on a carrier surface defined by multiple, movable, side-by-side support members and a plurality of fiber guides affixed on the support members for dispensing axial stuffer fiber strands as the carrier members move along predetermined paths to intertwine the fiber strands from the fiber guides. The carrier members are disposed on the support members for movement therewith and for movement from one support member to abother. The fiber guides are affixed on the support members for movement only with the respective support member. The stuffer fiber strand for each fiber guide is dispensed from a spool that is carried on a respective support member or is mounted on a stationary base.

摘要： A water soluble sizing for fibrous carbonaceous material consists of either 1,3-diglycidyl-5,5-dimethylhydantoin or 1,3-diglycidylhydantoin. The carbonaceous material is sized by immersion in an aqueous solution of the sizing having a concentration of 0.1-10%, preferably 1-2%, by weight, followed by drying. In addition to being highly water soluble, non-toxic and non-flammable, the sizing provides excellent filament control so as to minimize fuzzing during subsequent handling of the carbonaceous material and is compatible with an epoxy resin matrix system.

摘要： A composite gas turbine engine blade is made by braiding a plurality of fibers to form a preform having an airfoil precursor portion and an integral root precursor portion. A plurality of fiber shaping inserts are positioned in the root precursor portion, either by braiding the root precursor portion around the inserts or inserting the fiber shaping inserts into the root precursor portion after braiding, to impart an enlarged, divergent shape (e.g., dovetail precursor shape) to the braided root precursor portion. The braided preform with the enlarged, shaped root precursor portion is infiltrated with matrix material and shaped to near net shape to provide the composite blade with a dovetail shaped root.

摘要： There is disclosed a method of treating carbon fibers to provide an epoxy resin finish thereon. An aqueous emulsion of an epoxy resin is applied to the fibers and the fibers are thereafter dried. An effective amount of two different emulsifying components are used in the epoxy resin emulsion. One of the emulsifying components is a long chain aliphatic alcohol containing from eight to 18 carbon atoms. The other emulsifying component is a quaternary ammonium salt having the formula: ##STR1## wherein R is an aliphatic radical containing from 12 to 18 carbon atoms, or a mixture of such radicals, each R' may be the same or different radicals selected from methyl and ethyl, and x is bromine or chlorine.

摘要： A plurality of generally parallel, side-by-side warp tows of carbonaceous precursor material are interwoven with fill yarns forming a fabric of low density cross weave to facilitate handling of the warp tows for oxidation, carbonization and other processing thereof. A different fill yarn is interwoven with the warp tows from each of the opposite edges of the fabric so as to form a succession of generally V-shaped loops in each warp yarn with the loops of the two different warp yarns being staggered along the length of the fabric. Each loop of warp yarn is comprised of a pair of lengths of warp yarn which enter the fabric from spaced-apart locations along an edge of the fabric and undulate under and over the warp tows in a like sense which is opposite the sense of the undulations of the immediately adjacent loops prior to joining at a point across part but not all of the width of the fabric. When processing of the warp tows is completed, the fill yarns are easily removed simply by pulling on those portions of the fill yarns extending between the successive loops. Methods and apparatus for weaving the fabric employ spaced-apart members such as rotatable rollers for supporting the warp tows and reciprocating, out-of-phase heddle arrangement disposed between the rollers and engaging the warp tows to periodically momentarily lift alternate ones of the warp tows relative to the remaining warp tows and then momentarily lift the remaining ones of the warp tows relative to the alternate warp tows. Each time the warp tows are momentarily separated, a loop from each of the opposite fill yarns is placed between the separated warp tows such as by use of opposite rapier assemblies which employ hollow, elongated members for feeding in the warp yarns to form the loops.
摘要翻译：多个大致平行并排的碳质前体材料的经纱与交织的纱线与形成低密度交叉织物的织物的填充纱线交织在一起，以便于处理用于氧化，碳化和其它加工的经纱。不同的填充纱线与来自织物的每个相对边缘的经纱相互交织，以便在每根经纱中形成一系列大致V形的环，其中两根不同的经纱的线圈沿着面料。经纱的每个环都由一对长度的经纱组成，经纱的长度沿织物的边缘从间隔开的位置进入织物，并且以类似的方式在经纱之下和之上波动，这与起伏的感觉相反在连接到穿过织物的部分但不是全部宽度的点之前的紧邻的环之间。当经纱丝束的加工完成时，通过拉伸在连续的环之间延伸的填充纱线的那些部分，可以容易地去除填充纱线。用于编织织物的方法和装置采用间隔开的构件，例如用于支撑经纱的可旋转辊，以及布置在辊之间的往复式，异相综丝布置，并与经纱丝束接合以周期性地暂时提升交替的经纱相对于剩余的经纱丝，然后相对于交替的经纱丝束暂时提升其余的经纱。每当经纱丝束瞬时分离时，来自每个相对的填充纱线的环路被放置在分离的经纱之间，例如通过使用相对的剑杆组件，所述相对的剑杆组件采用中空的细长构件，用于进给经纱以形成环。
