A composite of metal and carbon-fiber-reinforced plastic according to the present invention comprising a predetermined metal member, a resin layer positioned at a surface of at least part of the metal member and containing an inorganic filler having a thermal conductivity of 20 W/(m.Math.K) or more, and carbon fiber reinforced plastic positioned on the resin layer and containing a predetermined matrix resin and carbon reinforcing fiber present in the matrix resin, the carbon reinforcing fiber being at least one of pitch-based carbon reinforcing fiber having a thermal conductivity of 180 to 900 W/(m.Math.K) in range or PAN-based carbon reinforcing fiber having a thermal conductivity of 100 to 200 W/(m.Math.K) in range, a content of the inorganic filler in the resin layer being 10 to 45 vol % in range with respect to a total volume of the resin layer, a number density of the inorganic filler present in a region of a width X m from an interface of the resin layer and the carbon fiber reinforced plastic in a direction of the resin layer being 300/mm.sup.2 or more, where X m is an average particle size of the inorganic filler.
Skin-bonded threaded inserts, sandwich panels including the same, and related methods
Skin-bonded threaded inserts may be installed within a sandwich panel by curing the insert in place as the sandwich panel is cured. Skin-bonded threaded inserts may include a collar that is transitioned between a raised position and a compressed position during installation of the skin-bonded threaded insert in the sandwich panel, due to compression of the sandwich panel during curing. Skin-bonded threaded inserts may include one or more flanges that engage one or more skins of the sandwich panel. Such flanges may be positioned between two skins, or between the core and a skin of the sandwich panel to secure the sandwich panel in place within the sandwich panel. Skin-bonded threaded inserts may be positioned within a sandwich panel without the use of potting compound and may engage with the skins of the sandwich panel, rather than relying on adherence to the core for sufficient pull-out and shear strength.
Inverted Injection Method of Affixing a Termination to a Tensile Member
A method for attaching an anchor to an end of a tensile member by inverting the assembly of anchor and tensile member and injecting pressurized potting compound. A length of filaments of the tensile member are placed within a cavity through the anchor. The anchor and filaments are placed in an inverted position, with the distal end of the anchor facing downward and the cable extending upward out of the anchor. If the anchor has an open distal end this is sealed. Liquid potting compound is injected into the anchor cavity and allowed to solidify. During the solidification process, a controlled translation (pulling) of the cable is preferably introduced.
Multi-Stage Additive Manufacturing Process With Inserts
According to one aspect of the disclosure, a method of manufacturing an implant may comprise manufacturing a first portion, coupling an insert with the first portion to form a combined first portion and insert assembly, and additively manufacturing a second portion on the assembly after the coupling step.
Metal-resin composite material, method for producing the same, and aluminum substrate having aluminum oxide coating
A metal-resin composite material including an aluminum substrate having an aluminum oxide coating and a resin bonded to the aluminum substrate through the aluminum oxide coating, wherein the aluminum oxide coating has a porous surface layer in which columns with an average height of 10 to 100 nm are arranged in a dispersed state, an average value of sums of cross-sectional areas of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 8000 to 128000 nm.sup.2, an average value of sums of circumferential lengths of cross-sections of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 1000 to 27000 nm, and an average value of numbers of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 10 to 430.
MANUFACTURING METHOD FOR FIBER-REINFORCED PLASTIC COMPOSITE
Provided is a method for manufacturing a fiber-reinforced plastic composite containing a fiber-reinforced plastic part having a plate-like portion and a rib protruding from one surface of the plate-like portion, and a metal part, having an average thickness of 0.5-3.0 mm, laminated on part of or all of the plate-like portion of the fiber-reinforced plastic part, comprising: a lamination step for stacking a plurality of incised prepreg layers as a plurality of sheets of base material to form a base laminate, each prepreg layer containing unidirectionally oriented fibers and resin, and a plurality of incisions crossing the fibers, a base material heating step for heating the base laminate, and a molding step for integrating the base laminate and the metal part by pressing them between a rib molding member having a recessed portion for forming a rib and a skin molding member free of such a recessed portion in a pressing device.
METHOD OF PRODUCING THERMOPLASTIC RESIN-IMPREGNATED SHEET-SHAPED REINFORCING FIBER BUNDLE
A method produces thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle obtained by impregnating reinforcing fibers made from continuous fibers with a thermoplastic resin, said method including: an application step in which a sheet-shaped reinforcing fiber bundle obtained by arranging reinforcing fibers made from continuous fibers in one direction is passed through an application section which retains thermoplastic resin, and the thermoplastic resin is applied to the sheet-shaped reinforcing fiber bundle to constitute a thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; a further impregnation step in which the applied thermoplastic resin is further impregnated into the inside of the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; and a shaping step in which the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle is shaped and solidified by cooling.

CO-MOLDING OF NON-CRIMPED FABRIC AND SMC
Co-molding of non-crimped fabric and sheet molding composition. The pre-preg of non-crimped fabric is dried to achieve suitable stiffness for molding. The pre-preg allows the pre-formed non-crimped fabric feature to retain its shape during molding. A plurality of thorns is provided in the molding tooling to further prevent movement of pre-preg during molding. The method of co-molding includes, drying of the pre-preg to achieve suitable stiffness for molding, pre-forming of the pre-preg, and incorporating a plurality of stand-off features or thorns in the molding tool to prevent movement of pre-preg during co-molding so that predetermined full coverage of non-crimped fabric is maintained in predetermined area(s) of the molded part and the continuous fibers of the non-crimped fabric are not distorted.
Friction damped component for highly stress engineering components
Damped highly stressed engineering components are disclosed. The disclosed inventive concept provides a method and system for increasing the damping capacity of an engineering system by adding a non-flat solid, highly damped insert to a system component that contributes most to the system's dynamic response. A friction damped insert can either be embedded into the damped components during casting or fastened to the outer surface of the damped component. The insert is made of the single layer of flexible material by forming it into a rigid elongated body. The layer of material can be turned over on itself without folding to create a cylinder or can be folded over a number of times to create a prismatic bar. The layer of material may be shaped into a corrugated panel. The layer of flexible material may have a number of relatively small openings or perforations with a uniform spatial distribution.
