Layup of Carbon fiber
Carbon fiber prepreg cloths vary in modulus and tow which are cut into smaller patches according to the chart of layup which might vary from each frame model and size. For example, Velocity Geos is having four sizes so this means that for the one model there would be four unique charts of layup which are closely related to each other, but still not very identical. This is an example of an actual engineering diagram of layup for the Velocite Geos location, carbon fiber grade and orientation information which might be deleted for confidentiality reasons. There would be 8 layers in total by using three different types of carbon fiber. Our layup is optimized for handling specific directional loads of acting on the frame. This means that for example, in the down tube, top tube, seat stays and the chain stays, the layup had prioritized for handling of torsion forces to be used.
Importance of lying down
The importance of laying down patches of carbon fiber prepreg in different orientations could be due to carbon fiber with maximum strength only along the lengths of the fibers. This has also helped in illustrating why we are using uni- directional fiber instead of woven carbon fiber that had created stronger frames. When we use woven carbon fiber, at any one time half of the fibers are not oriented so that the force acts along their length. Of course using multiple layers of woven carbon fiber in different orientations would be helpful in mitigating this to some extent. However, the other problem with woven fabrics has been localized bending of the fibers as the weaves pass across each other. This deficiency affects all woven carbon fibers and cannot be overcome easily. Thus, the main use of woven carbon fiber when it comes to bicycle frames is for appearance.
Harris Communications has introduced the new innovation of cell phone antenna repeater which is designed to meet all specifications of new regulations set to go into effect March 1, 2014, by the Federal Communications Commission. This new line of cell phone signal amplifiers will reduce interference with the help of wireless networks across the country and will enable wireless users in order to take the advantages of Harris Communications’ technology also meets the mandates of the new FCC regulations. Harris Communications’ cellular signal repeaters are designed to meet the FCC standards which reduce and eliminating interference from wireless devices which sometimes interrupt emergency calls while delivering excellent reception and transmission with no effect on users’ wireless service. The FCC compliant cell phone repeaters for office or home will produce flawless connections with the major wireless providers.
Cell phone repeater antenna for home is useful
Cell phone repeaters or wireless cell phone amplifier(bi-directional amplifiers), such as Yagi antennas produced by Harris Communications, provide the most common way cell phone companies have been improving cellular coverage over the past few years. Technology refined by Harris Communications for more than 20 years have virtually eliminated calls dropped mid sentence. Their bi-directional amplifiers boosts cell phone signals by using superior internal rebroadcast antennae in conjunction with a reception antenna and a signal amplifier. These aid the cellular broadcast towers that network providers base their signals from. These cell phone repeater antennae are smaller and are used inside a building to improve cellular coverage inside when the walls might hinder a signal. The signal from main cellular towers sometimes is unable to get through thick concrete, which can weaken cellular coverage. Harris Communications’ advanced versions of bi-directional amplifier units allow more than one cell phone to use them at the same time, whereas the older, original equipment on the market in the past could only be used by one cell phone at a time.
