Abstract:
This invention relates to an FRP structural member comprising reinforcing fibers, which comprises carbon fibers (a) having tensile modulus of 400 to 850 GPa, in which the carbon fibers (a) are placed so that the orientation direction of the carbon fibers (a) becomes parallel to the longitudinal direction of the structural member. The FRP structural member has high vibration-damping property and much lower production cost as well as light weight, high rigidity and superior corrosion property.
Abstract:
A laminated strength-reinforced window assembly comprises a sheet of strength-reinforced transparent material, first and second transparent windowpane sheets. The strength-reinforced sheet has a tensile strength value, an impact resistance value, an environmental resistance value, an upper sealing surface and a lower sealing surface. Each windowpane sheet has a respective tensile strength value, impact resistance value and environmental resistance value. The first sheet is disposed over at least a part of the upper sealing surface and the second sheet is disposed under at least a part of the lower sealing surface. At least one of the tensile strength value, the impact resistance value and the environmental resistance value of the strength-reinforced material is significantly greater than the corresponding value of one of the first and second windowpanes. The windowpane sheets are hermetically bonded to the sheet of strength-reinforced material without non-hermetic adhesives to form a continuous hermetic joint therebetween.
Abstract:
Fiberboard to protect sensitive electronic components and devices from the hazards of ESD (electrostatic discharge) incorporates a homogeneous conductive shielding paperboard having an electrical resistance of less than or equal to one thousand ohms resistance that has been adhered together throughout the corrugation process or lamination process with one or more homogeneous static dissipative linerboards. The liners have a surface resistance range between a targeted 1null107 to 1null1011 at twelve percent relative humidity and 73null Fahrenheit. The static dissipative linerboard and conductive shielding paperboard can be used as static safe packaging cushioning material, shelving liners, dividers, in-plant handlers, specialty static free packaging, and dissipative or shielding paper bags.
Abstract:
The invention concerns a web comprising an intimate mixture of mixed slivers of long reinforcing staple fibres (14) obtained by stretch-breaking and long thermoplastic matrix fibres (15), those different fibres being parallel in the mixture.
Abstract:
A liquid dispensing module dispenses multiple filaments of adhesive material from a single die to coat multiple strands of a substrate material. The liquid filaments are dispensed primarily in an oscillatory or back and forth manner such that each filament coats multiple strands of the substrate material. This results in a coated substrate that exhibits more uniform characteristics across the strands after they are secured to a substrate or substrates.
Abstract:
In a mounting structure including a first electrode and a second electrode electrically connected to each other via a conductive adhesive, the periphery of an adhesion portion between at least one of the electrodes and the conductive adhesive is covered with an electrical insulating layer, whereby the adhesion portion is reinforced from the periphery. The electrical insulating layer may be formed by dissolving a binder resin component of the conductive adhesive in a solvent. This increases the concentration of a conductive filler in the conductive adhesive, so that the conductivity of the adhesion portion is also enhanced.
Abstract:
A headliner (10) for use with a motor vehicle including a combination of a chopped fiber roving (22) bonded between a non-woven film layer and a urethane core (14) to eliminate warpage in the headliner (10) after the molding and forming process is complete. The combination of stiffness and mechanical bond provides this effect. The combination may also include a polypropylene non-woven material (18) combined with a polyethylene film (20) to form a laminate top (12) and bottom layer (16). The chopped fiber roving (22) is randomly disposed between the laminate (21) and a urethane matrix (44) used to form a core (14) of the headliner (10) to provide the shape stability to the headliner (1).
Abstract:
A fabric system for producing at least a woven fabric of controlled modulus or elongation in the MD or warp axis, has a core layer which is the main structural element, and may have one or more woven cover fabrics adhesively bonded with an off axis configuration to one or both sides of the core layer. In a preferred embodiment the core fabric is covered with at least one off axis fabric on both sides. The cover fabrics may also have resin or film top layers laminated or coated on their outside surfaces, for mechanical performance or UV protection or both.
Abstract:
A filter screen is made of metal or synthetic strands having reinforcing filaments regularly spaced in the cross machine and the machine directions.
Abstract:
A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. To the collated fibers is applied a resin so as to permeate through the layers and the materials are passed through a die to set the resin. The first and second layers are arranged to form first and second opposed surfaces of the part with the intermediate layer therebetween. The resin is a two part urethane resin which has sufficient strength to prevent the fibers from the first and second layers at the first and second surfaces respectively from breaking through the surface on bending of the wall thus allowing the use of the rovings at the surfaces with the transverse fibers therebetween so that the transverse fibers can be formed from loose or chopped fiber material from rovings rather than more expensive mat.
