  • Patent number: 9555606
    Abstract: Assembly apparatuses and processes are provided which include a pressure cure fixture. The pressure cure fixture is sized to reside within a container, such as an electronic enclosure, and facilitate applying pressure to an adhesive disposed over an inner surface of the container. The pressure cure fixture is formed of a material with a higher coefficient of thermal expansion (CTE) than the container, and is sized to correspond, at least in part, to an inner space of the container while allowing for the adhesive and a surface-mount element to be disposed between the pressure cure fixture and the inner surface of the container. When heated, the pressure cure fixture expands greater than the container and imparts the pressure to the surface-mount element and the adhesive to facilitate securing the surface-mount element to the inner surface of the container.

  • Patent number: 9448045
    Abstract: The high straightness arrow in the present invention is designed to improve the straightness of the archery arrow by adopting new manufacturing technique and method. Chamber and post are made of dissimilar metals and the chamber includes a wall that creates an external housing and defines an internal airspace. Once the post with shaft is positioned through chamber, nuts are tightened securely, forming an assembly, to straighten post. Due to the different coefficients of thermal expansion of chamber and post, when they are heated simultaneously, the chamber expands more than the post, creating a natural tension along post which results in a near perfectly straight shaft. As the assembly cools, the post and chamber return to their original length, yet the shaft retains its straightened form and thus this manufacturing process yields an arrow shaft that is straighter than shafts made of the same materials but with a traditional manufacturing technique.

    Abstract: A method for demolding concrete blocks which are cast in a resilient mold supported in a rigid frame, the mold having a top surface and at least one cavity with an opening on the top surface, which cavity holds a cured cast concrete block. The mold has two opposing edges. The demolded blocks are stacked on a collection surface. A support is positioned over the cavity and the mold, the support and the frame are inverted and positioned in demolding apparatus. After two opposing edges of the mold are engaged by the demolding apparatus, the support is withdrawn to allow the mold to sag. The blocks may release from the mold and fall onto the collection surface. If any blocks remain in the mold, a plunger mechanism is pushed against the sagging mold to release the blocks. Guide members may facilitate positioning the blocks on the collection surface.

    Abstract: A method and apparatus for fabricating a composite part, such as a fuselage or internal stiffener, with a shape memory polymer (SMP) apparatus usable as both a rigid lay-up tool and a bladder. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. For example, cavities may be formed into the SMP apparatus for nesting components therein to co-bond or co-cure with the composite part. Next, composite material may be applied onto the SMP apparatus and then placed into a rigid external tool and heated to composite cure temperatures at which the SMP apparatus is malleable. A pressure differential may be induced which urges the SMP apparatus to compress the composite material against the rigid external tool. When the composite material is cured, the SMP apparatus may be urged away from the cured composite material and removed from within the composite part.

  • Patent number: 8734703
    Abstract: A method and apparatus for fabricating a composite part with a shape memory polymer (SMP) apparatus usable as both a rigid lay-up tool and as a bladder. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. For example, cavities may be formed into the SMP apparatus for nesting components therein to co-bond or co-cure with the composite part. The composite material may be applied onto the SMP apparatus in the rigid tool configuration and then placed into a rigid external tool and heated to composite cure temperatures at which the SMP apparatus is malleable. A pressure differential may be induced which urges the SMP apparatus to compress the composite material against the rigid external tool. When the composite material is cured, the SMP apparatus may be urged away from the cure composite material and removed from within the composite part.

  • Patent number: 8734925
    Abstract: Composite pre-forms are molded at high pressure to form composite parts that can be used in place of metal-based high performance parts, such as the outlet guide vanes found in turbofan jet engines. The composite pre-forms include two different fiber orientations that are co-molded in a resin matrix at high pressures to provide composite outlet guide vanes and other high performance parts. Chambers within the composite part are optionally formed during molding of the pre-form at high pressures.

  • Patent number: 8734704
    Abstract: The present invention relates to a method of fabricating a mold core (5) for making hollow parts (11) based on a composite material including fibers, fabrics, or textiles together with a resin, the method consisting in mixing a filler material (1) and a binder material (2) in order to obtain a uniform mixture of materials, and in solidifying, compacting, and shaping the resulting mixture in order to constitute said core, the method being characterized in that it further consists in introducing into the mixture at least one complementary material (3) that is expandable under the effect of heat or by applying another physical or chemical principle, and in mixing said materials (1, 2, 3) in order to obtain a uniform distribution of the complementary material (3) in the mixture.

  • 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: 8715558
    Abstract: A seamless microchannel with aligned microelectrodes structure can be prepared to include a polymeric body defining a surface of a seamless microchannel. The microchannel is seamless in that it is formed by a single body of material having a conduit that is open at one surface and extends to another opening aligned with microelectrodes in another surface of the body. The rest of the microchannel is closed and defined by the single body of material. The seamless microchannel structure can be used in methods that include biosensors, coupling waveguides, capillary electrophoresis chips, microreactors, polymerase chain reaction-chips, and solving mathematical problems.
