摘要： Systems and methods for producing a preform for a composite member. An exemplary method includes preparing a lay-up of reinforcement layers and thermoplastic interlayers, and transferring the lay-up to a preform tool. The method further includes inducing heat in the preform tool to a transition-temperature range that causes the thermoplastic interlayers to become tacky or viscous, and applying pressure to the lay-up with the preform tool to shape the lay-up into the preform.

摘要： A method of making a coated polymer-matrix composite (PMC) having high-temperature oxidation protection includes bonding a first surface of a flexible sublayer that is free of water to a first surface of a dry PMC substrate having a first coefficient of thermal expansion. The flexible sublayer includes an electrically conductive material in an effective amount to enable electrical conductivity of the flexible sublayer, and includes a low-modulus-of-elasticity material. The method includes heating the bonded flexible sublayer and the PMC substrate, and bonding a first surface of an oxygen-impervious, dense barrier-coating layer to a second surface of the flexible sublayer to form the coated PMC having high-temperature oxidation protection. The dense barrier-coating layer includes metallic materials and ceramic materials, each having a respective second coefficient of thermal expansion, and flexibility of the flexible sublayer protects the respective bonds when the first and second coefficients of thermal expansion are unequal.

摘要： A method and apparatus for manufacturing. A fiber layer and a first porous bonding layer are formed to form a unidirectional lay-up of fibers. The unidirectional lay-up of fibers is heated under pressure to form a unidirectional composite tape. A first plurality of lengths of the unidirectional composite tape is laid down to build a first layer from the unidirectional composite tape. A second plurality of lengths of the unidirectional composite tape is laid down to build a second layer from the unidirectional composite tape on the first layer at a predetermined angle from the first layer. At least one of the first and second plurality of lengths of the unidirectional composite tape are slit while laying down the first and second plurality of lengths of the unidirectional composite tape. A composite fabric is formed from the first and second layer.

摘要： A method for forming a ceramic-based material comprises depositing a ceramic-precursor composition comprising nanoparticles having at least one dimension less than 100 nm and an aspect ratio of 1.5 or greater, and a carrier fluid on a surface of a substrate to form an as-deposited layer of the ceramic precursor composition; and sintering the as-deposited layer of the ceramic precursor composition at a sintering temperature to form a ceramic-based material.

摘要： A method for fabricating a stiffened panel. Layers of composite material are placed on a surface of an inner-mold-line tool having protrusions that extend from the surface of the inner-mold-line tool. The layers of composite material laid-up on the surface of the inner-mold-line tool are compacted to form compacted layers of composite material. The compacted layers of composite material are cured to form an inner-mold-line layer having corresponding protrusions. The inner-mold-line layer is joined to an outer-mold-line layer.

摘要： There is provided a method of making a hollow fiber. The method includes mixing, in a first solvent, a plurality of nanostructures, one or more first polymers, and a fugitive polymer which is dissociable from the nanostructures and the one or more first polymers, to form an inner-volume portion mixture. The method further includes mixing, in a second solvent, one or more second polymers to form an outer-volume portion mixture, and spinning the inner-volume portion mixture and the outer-volume portion mixture to form a precursor fiber. The method further includes heating the precursor fiber to oxidize the precursor fiber and to change a molecular-bond structure of the precursor fiber, and during heating, extracting the fugitive polymer from the inner-volume portion mixture. The method further includes obtaining the hollow fiber with the inner-volume portion having the nanostructures and the first polymers, and with the outer-volume portion having the second polymers.

摘要： Water-entrained compositions comprising colloidal or suspensoidal solutions comprising polyimide pre-polymers/oligomers are described. These compositions are obtained in water by initial dispersion of the resin constituents in water to from colloids or suspensoids. The water-entrained polyimide compositions can be applied to numerous surfaces or more beneficially used for composite fabrication. The coated surfaces or polyimide-pre-polymer impregnated reinforcing materials are subsequently cured and are ideal for providing thermal protection.

The method further includes mixing in a second solvent one or more second polymers to form an outer-volume portion mixture, spinning the inner-volume portion mixture and the outer-volume portion mixture and extracting the fugitive polymer from the inner-volume portion mixture to form a precursor fiber, heating the precursor fiber to oxidize the precursor fiber and to change a molecular-bond structure of the precursor fiber, and obtaining a hollow fiber with the inner-volume portion having the nanostructures and the first polymers, and with the outer-volume portion having the second polymers.
