The support apparatus may comprise a rigid structural member and a plurality of SMP cells attached thereto and configured to inflate or deploy in a malleable state toward and against a surface of the SMP apparatus, mold, or mandrel. Then the SMP cells may be returned to a rigid state while still pressed against this surface, thereby providing structural support when composite material is applied to an opposite surface of the SMP apparatus, mold, or mandrel. After the composite material is cured into the finished composite part, the SMP cells may be deflated or otherwise collapse toward the structural member to provide enough clearance to be removed from the cured composite part.

  • Patent number: 8939753
    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.

  • Patent number: 8777603
    Abstract: Embodiments of the invention are used to provide ways of tire tread molding and retreading with a double tread rubber body having a unitary structure that comprises two treads in order to remove the need for buffing an oxide layer typically associated with tread molding and curing. Embodiments of the double tread molding and retreading methods also remove the need for cementing the cured tread to prevent future oxidation buildup. Once the double tread is cured and cooled, it is cut along the centerline with a double tread separation apparatus to expose a soft non-oxidized inner rubber. The cutting is much less energy intensive when compared to buffing with an expendable wire brush. There is no risk of spots of oxidized rubber being missed as is the case with buffing. There is little or no dust created.

  • Patent number: 8651850
    Abstract: The invention concerns a device for stiffening a flat component, a process for the production of a flat component, in particular a fiber composite component, and a fiber composite component. The device has a portion for producing a space for receiving a mold core for the transmission of a pressure for pressing the flat component and the device. It is characterised by means for positively lockingly and/or frictionally lockingly positioning the mold core in the space of the device. The process according to the invention includes the following steps: introducing the mold core into the portion of the device, positively lockingly and/or frictionally lockingly positioning the mold core in the portion of the device by means of the means, applying the device including the mold core to the non-hardened material layer or layers, pressing the material layers, and hardening the material layer or layers and joining the device to the material layer or layers.

  • Patent number: 8617444
    Abstract: Equipment and methods for preparing curved fibers in a batch or continuous process. Fiber strands comprising a thermoplastic material are placed on a cylindrical surface and heated such that they soften and become malleable. The fiber strands assume the curvature of the cylindrical surface and, upon cooling below their softening temperature, retain the curvature. The curved-fiber strands are then cut to a desired length.

  • Publication number: 20130288035
    Abstract: A polymer opal material comprises a three dimensionally periodic arrangement of core particles in a matrix material and exhibits structural colour via Bragg reflection. IN a process for manufacturing such a material, a sandwich structure is provided, of a precursor composite material held between first and second sandwiching layers. A relative shear strain of at least 10% is imposed on the precursor composite material by curling the sandwich structure around a roller. The shear strain is cycled, in order to promote the formation of the three dimensional periodic arrangement.

  • Patent number: 8523553
    Abstract: An apparatus and methods for forming a composite part are provided. A method for forming a composite part may include placing initial composite material on a base tool, placing a tooling mandrel on the composite material, placing additional composite material over the tooling mandrel, covering at least a portion of the composite material that overlays the tooling mandrel with a composite forming tool, heating the composite material to at least partially cure the composite material, and permitting a first portion of the composite forming tool to change size during the heating of the composite material to a greater degree than a second portion of the composite forming tool. In this regard, the second portion of the composite forming tool is closer to the base tool than the first portion of the composite forming tool. A composite forming tool is provided that permits differential expansion of different portions of the tool.

    Abstract: A belling machine (1) forms end sockets equipped with an integrated seal on pipes (3) made of thermoplastic material using a forming mandrel (4) on which an annular seal (5) was previously placed, diametrically expanded, coaxially and in a predetermined position. A loader (8) for loading the annular seal (5) on the mandrel (4) is able to move between a arming position, in which the loader is spaced from the belling axis (b) and does not interfere with the mandrel (4) movement along the belling axis (b), and a loading position, in which the loader is coaxial with the belling axis (b) and is located between the mandrel (4) back position, disengaged from the pipe (3) and the mandrel (4) forward position, inserted in the end (30) of the pipe (3). An annular seal (5) is placed in a positioner (10) which holds it in an operating position for the action of an arming device (9).

  • Publication number: 20130200551
    Abstract: Thermoforming apparatus and methods are described. To-be-formed polymeric material may be separated initially from a mold surface by a grid or support rail, avoiding the mold surface from drawing heat away from the material while it is being heated to forming temperatures. The grid may retract into the mold when no longer needed to support the material. Plugs or inserts about which material is formed may include skirts, allowing the formed material to be shaped so as to guide coins or other objects into cavities in which the coins or objects are held for presentation or display. Profile plates associated with the molds may include non-stick material on their sides intended to abut to-be-formed polymeric sheets in order to reduce possibility of transfer of printing from the sheets to the plates and reduce undesired transfer of heat from the plates to the sheets.
