A gasket is disclosed for use as an environmental seal between a first aircraft part having planer surface and a second aircraft part having a planer surface, the two planer parts spread apart and engaged with fasteners. The gasket, in some embodiments, is compressible between the planer surfaces. The gasket, in some embodiments, comprises a first tabular portion having tabular portion properties and having a first tabular thickness and a length and a width, the length and width much greater than the first tabular thickness; and a second tabular portion having tabular portion properties having a second tabular thickness, a length and width, the length and width much greater than the second tabular thickness; and a tabular skeleton. The first and second tabular portions and the skeleton are positioned parallel to one another. The skeleton is at least partly contacting one of the tabular portions. The first tabular portion and the second tabular portion differ in at least one tabular portion property.

A moulding material which comprises: (a) a structural reinforcement layer comprising a fibrous reinforcement material optionally in combination with a second resin composition; and (b) a surface enhancing layer, for contacting a surface of a mould or tool, comprising a first non-woven fibre carrier in combination with a first resin composition containing a rheology modifier and a curing agent, wherein the first resin composition provides an external mould or tool-contacting surface of the moulding material. The moulding material can be cured to form a moulded article having a high quality surface finish that requires minimal preparation before painting and/or application in its intended use. The moulded article may be provided with sacrificial discontinuous indicator means to assist in uniform removal of a part of the surface enhancing layer of the moulded article for specific applications.

Embodiments of the present invention describe secured fiber-reinforced aerogels and laminate structures formed therefrom. In one embodiment a laminate comprises at least one fiber-reinforced aerogel layer adjacent to at least one layer of fiber containing material wherein fibers from said at least one fiber-reinforced aerogel layer are interlaced with fibers of said at least one fiber-containing material. In another embodiment a laminate comprises at least two adjacent fiber-reinforced aerogel layers wherein fibers from at least one fiber-reinforced aerogel layer are interlaced with fibers of an adjacent fiber-reinforced aerogel layer.

Provided is a method for producing a decorated cycloolefin resin molded article, the method comprising curing a gel coat composition and polymerizing a cycloolefin polymerizable composition containing a radical generator while the gel coat composition is in contact with the cycloolefin polymerizable composition, thereby containing a decorated cycloolefin resin molded article including a gel coat and a cycloolefin resin layer adhering to each other.

The present invention aims at providing a prepreg for producing a laminate suitable as a structural material, and a laminate, which have excellent tensile shear joining strength, fatigue joining strength, and interlaminar fractural toughness values, and can be firmly integrated with another structural member by welding. The present invention is a prepreg including the following structural components [A], [B], and [C], wherein [C] is present on a surface of the prepreg, [C] is a crystalline thermoplastic resin having a glass transition temperature of 100° C. or higher or an amorphous thermoplastic resin having a glass transition temperature of 180° C. or higher, and the reinforcing fibers [A] are present which are included in a resin area including [B] and a resin area including [C] across an interface between the two resin areas: [A] reinforcing fibers; [B] a thermosetting resin; and [C] a thermoplastic resin.

A member for a semiconductor cleaning apparatus, including prepreg containing a carbon fiber and a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer which are thermally fused with each other, wherein the carbon fiber contains a carbon fiber in the form of a sheet.

A sole structure includes a compressible elastomer and a knitting texture wrapped around the compressible elastomer and fused with a surface of the compressible elastomer. The compressible elastomer is formed from the thermoplastic filling material after being melted and cooled. The knitting texture is formed from the knitted fabric and is capable of being directly observed from an appearance of the sole structure.

The present disclosure relates to multi-compound fiber reinforced composites and methods of making the same using frontal polymerization and targeted photosensitizer additives. In various aspects, the method may include disposing one or more layers in a mold cavity, where each of the one or more layers includes a fiber material and a first compound. The method may further includes disposing a second compound in the mold cavity, where the second compound includes a photosensitizer material. Further still, the method may include initiating photopolymerization of the photosensitizer using an ultraviolet light source, removing ultraviolet light source, and/or completing polymerization of the one or more layers so as to form the fiber-reinforced composite.

Provided is a method for manufacturing a fiber reinforced resin molded article capable of detecting a resin impregnation state in a fiber layer of a preform at a position corresponding to a resin flow end portion and uniformly impregnating the fiber layer of the preform with resin, and such a manufacturing device thereof. For example, when a relation between a resin pouring time and a pressure of resin detected by a pressure sensor satisfies a predetermined condition or when the pressure of resin detected by the pressure sensor is higher than or equal to a predetermined value, it is determined that the resin flow end portion of the preform is completely impregnated with resin.

The present invention discloses cured composites having improved surfaces and processes of making and methods of using same. Such processes use ultra-short pulse lasers, for example, a femto-second laser to ablate material without the detrimental heat affected zones of other laser processes. Such process can not only increases surface roughness and clean contaminates, but can also selectively remove the matrix material and expose the surface fibers of cured composites. The treated cured composites have improved thermal and electrical pathways that can dissipate unwanted heat and electricity when two or more prepregs and/or cured composites are bonded or cured to form a single article.
