Abstract: A hybrid single or multilayer composite reinforcement system is disclosed. The system is configured to install or apply around the existing power transmission lines, for example, ACSR transmission lines for increasing ampacity and also decreasing sag of the power transmission lines. The hybrid composite system comprises a first layer, a second layer, and a composite core as a structural reinforcement component. The first layer and second layer are formed using a fiber reinforced resin composite material, comprising a basalt fiber and the structural reinforcement component is a carbon fiber. The composite core is disposed between the first layer and second layer. Further, the first layer and second layer are cured, thereby making the multilayer hybrid composite reinforcement system. The composite core, comprising for example carbon fiber, provides structural strength for the hybrid composite system.

Abstract: A method of reinforcing a structural element is disclosed. The method comprises positioning a first rigid fiber-reinforced shell extending between first and second edges partially about an external surface of the structural element to leave an exposed portion of the structural element. The method also comprises positioning a second rigid fiber-reinforced shell extending between first and second edges about the exposed portion of the structural element such the first edge of the second rigid fiber-reinforced shell adjacent the first edge of the first rigid fiber-reinforced shell to give a first seam and the second edge of the second rigid fiber-reinforced shell is adjacent the second edge of the first rigid fiber-reinforced shell to give a second seam. Finally, the method includes adhering the first and second rigid fiber-reinforced shells to the structural element. A reinforced structural element produced by the method is also disclosed.

Abstract: A method of forming a structural composite is disclosed. The method comprises combining an uncured resin and a carbon fiber textile to form a first layer. The method also comprises forming a second layer comprising uncured concrete adjacent the first layer, wherein the uncured concrete of the second layer is in contact with the uncured resin of the first layer. Finally, the method comprises curing the first and second layers, thereby forming the structural composite. A structural composite produced by the above method is also disclosed.
