  • Patent number: 8765048
    Abstract: The present invention generally relates to a mold assembly (32, 34) and a method of using the mold for the manufacture of composite parts which, more particularly, are generated from a strengthener in a generally solid phase and a matrix in a generally liquid phase. Various types of molds and processes may be used in order to impregnate a strengthener with a matrix such that a composite part may be manufactured, but the efficiency rate and the duration of the manufacturing process significantly varies depending on the chosen type of mold and process. The present invention relates to a mold assembly and to the manufacture of composites by using the mold assembly which includes the injection of the matrix in the mold assembly containing the strengthener and a deformable member (36) which favors the impregnation of the matrix toward the strengthener.

  • Patent number: 8721959
    Abstract: A system for self-repairing matrices such as concrete or cementitous matrices, polymeric matrices, and/or fibrous matrices, including laminates thereof The system includes repair agents retained in and/or on vessels, such as hollow fibers, within the matrix. Upon impact, the vessel rupture, releasing the chemicals. For multi-layer laminates, the systems provides a total dynamic energetic circulation system that functions as an in situ fluidic system in at least one layer or area. The energy from the impact ruptures the vessels to release the chemical(s), and mixes the chemical(s) and pushes the chemical(s) and/or resulting compound through the matrix. The repair agents can withstand high temperatures, such as the heat of processing of many laminates, e.g., 250-350° F.

  • Patent number: 7749424
    Abstract: A method of making a fenestration framing member includes providing a core of desired cross section and geometry lengthwise of the core. A fiberglass mat is placed around the core to form a fiberglass-enclosed core, and resin is vacuum infused into the mat to form a fenestration framing member that includes fiberglass-reinforced resin enclosing the core. The starting core and the final fenestration framing member preferably are of curved geometry lengthwise of the core and member. The step of vacuum infusing resin into the mat surrounding the core preferably is carried out by placing the fiberglass-enclosed core into a vacuum enclosure, preferably a vacuum bag, and connecting the vacuum enclosure to a vacuum source and a resin source.

  • Patent number: 7442542
    Abstract: Disposable units in current use for performing PCR are limited by their heat block ramping rates and by the thermal diffusion delay time through the plastic wall as well as by the sample itself. This limitation has been overcome by forming a disposable plastic chip using a simple deformation process wherein one or more plastic sheets are caused, through hydrostatic pressure, to conform to the surface of a suitable mold. After a given disposable chip has been filled with liquid samples, it is brought into close contact with an array of heating blocks that seals each sample within its own chamber, allowing each sample to then be heat treated as desired.
