  • Patent number: 9394199
    Abstract: A surface-modified fibrous material is provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article. Good binding between the fibrous material and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The fibrous material may be provided in continuous or discontinuous form. In a preferred embodiment glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. The surface-roughened fibrous material is incorporated in a thermoplastic matrix as fibrous reinforcement with the application of heat whereby the thermoplastic matrix is rendered melt processable. In preferred embodiments injection or compression molding is utilized.

  • Patent number: 8378094
    Abstract: Coupling-initiator compounds are described that include a silicon-containing coupling moiety and at least one polymerization initiator moiety. The coupling moiety may be linked to the at least one polymerization initiator moiety by at least one linking moiety. The coupling moiety is capable of coupling the compound to a substrate, while the one or more polymerization initiator moieties are capable of initiating a polymerization of a monomer under polymerization conditions. The coupling-initiator compounds may be included in fiber reinforced polymer composites, where the compounds are coupled to the fibers in the composites and participate in the polymerization of the surrounding polymer.

  • Patent number: 7870324
    Abstract: A system and method for providing a serial communication bus is disclosed. A serial communication bus connects multiple footprint devices, such as electronic sensors in a process control sample system. The footprint devices can utilize various footprint device specific communication protocols. Multiple tophat devices act as general I/O ports for connecting with the footprint devices. Each tophat device identifies the footprint device specific communication protocol of a connected footprint device, converts outputs signals transmitted from the connected footprint device from the footprint device specific communication protocol of the footprint device to a standard bus communication protocol, and converts input signals directed to the connected footprint device from the standard bus communication protocol to the footprint device specific communication protocol of the footprint device.

  • Publication number: 20080160286
    Abstract: Surface-modified discontinuous glass fibers are provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article by injection or compression molding which displays enhanced mechanical properties, including improved tensile strength. Good binding between the discontinuous glass fibers and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. Improved color in the resulting injection or compression molded thermoplastic discontinuous glass fiber-reinforced composite articles is made possible in combination with enhanced mechanical properties.
