    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 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: 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.
