| 20110017384 | COMPOSITE FUSELAGE FOR VEHICLES - A method of assembling a vehicle includes providing a mandrel that approximates the shape of a fuselage to be formed, winding a fiber around the mandrel by rotating the mandrel with a driver, heating the fiber to form the fuselage having a structural, hardened shell, removing the mandrel from the fuselage, and mounting the fuselage onto a frame rail of the vehicle. | 01-27-2011 |
| 20120006468 | INLINE PLASMA TREATMENT OF AN OPTICAL FIBER CABLE STRUCTURE - To treat a surface of an optical fiber cable structure, substantially an entire length of the optical fiber cable structure is moved through an inline plasma treatment system. As the optical fiber cable structure is moved through the inline plasma treatment system, the surface of the optical fiber cable structure is continually exposed to plasma. Exposing the surface of the optical fiber cable structure to plasma modifies a characteristic of the surface of the optical cable structure to improve an ability of the surface of the optical fiber cable structure to adhere to a target material. | 01-12-2012 |
| 20140246141 | PRESSURE TUNABLE EXPANDABLE MANDREL FOR MANUFACTURING A COMPOSITE STRUCTURE - A method of making a composite core can include configuring a plurality of mandrels to have a desired thermal expansion characteristic, placing a composite material around each mandrel, placing the plurality of mandrels in a tool, the tool being configured to constrain the plurality of mandrels as the mandrels experience a thermal expansion, heating the mandrels so that the mandrels thermally expand, thereby applying a pressure to the composite material during a cure cycle, and then cooling and separating the mandrels from the composite core. The mandrel is configured as an internal form for making a tube member of a composite core. | 09-04-2014 |
| 20150290882 | HOOP WINDING DEVICE, FILAMENT WINDING APPARATUS AND MANUFACTURING METHOD OF TANK - There is provided a hoop winding device, comprising: a winding table configured to have an insertion hole formed to place a mandrel at a center thereof; a drive unit configured to rotate and drive the winding table; a plurality of supports on which bobbins with wound fibers are mounted, the plurality of supports being arranged along circumference of the winding table; a first guide section configured to bundle fibers drawn from a plurality of bobbins which constitute a first bobbin group out of the bobbins respectively mounted on the plurality of supports and feed the bundled fibers to the mandrel; and a second guide section configured to bundle fibers drawn from a plurality of bobbins which are not included in the first bobbin group but constitute a second bobbin group and feed the bundled fibers to the mandrel. | 10-15-2015 |
| 20150300792 | HIGH STRAIGHTNESS ARROW AND METHOD OF MANUFACTURE - 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. | 10-22-2015 |
