Description

Laminate plate for helinet frame and frame for helinet manufactured therefrom The present invention relates to a laminated plate for a helinet frame and a helinet frame manufactured therefrom, and more specifically, to a laminated plate for a helinet used on the helinet deck of a surface ship used by the Navy or Coast Guard, which has excellent strength as well as excellent seawater corrosion resistance, and a helinet frame manufactured therefrom. Generally, heline nets are installed at helicopter landing sites for safety. These heline nets are installed on land, outdoors, or at other locations. However, among these helinets, those used on the helicopter decks of surface ships operated by the Navy or Coast Guard must have seawater corrosion resistance since they are installed on surface ships operating at sea; however, there was a problem in that the helinets currently in use are made of steel and do not have sufficient corrosion resistance. In addition, as shown in Fig. 1, the heline net used on a surface ship is erected on the inside of the helicopter deck to prevent crew members from drowning when the helicopter is not taking off or landing, and is used as a safety railing; therefore, the heline net must have sufficient strength and be lightweight at the same time. Figure 1 is a conceptual diagram of a helicopter deck with a heline net installed. Hereinafter, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. The present invention may be embodied in various different forms and is not limited to the embodiments described herein. In the drawings, parts unrelated to the explanation have been omitted to clearly explain the present invention, and the same reference numerals are assigned to identical or similar components throughout the specification. Referring to FIG. 1, which is a conceptual diagram of a helicopter deck with a heline net installed, the heline net is a net installed on the side of the helicopter deck (10) to prevent safety accidents when a helicopter lands on the helicopter deck (10). When a helicopter is not landing, it is positioned upright to be configured in the form of a railing as shown in FIG. 1 (b) to prevent crew members from falling. These heline nets (20) are mainly made of steel to prevent safety accidents such as falling, but since they are installed on the helicopter deck (10) of a surface vessel used by the Navy or Coast Guard, there is a problem of damage caused by corrosion, and since the operation of unfolding and setting up the heline net (20) is performed repeatedly before and after the helicopter lands, there is a problem of the frames of the heline net (20) separating from each other. To solve these problems, the frames of the heline net (20) are fixed using separate fasteners, but they have not shown great effectiveness due to repeated use and exposure to corrosive environments. To solve these problems, this patent enables the provision of a helinet frame with strong seawater corrosion resistance and high durability by manufacturing the helinet frame using the laminated plate for the helinet frame of the present invention. The laminate for a helinet frame of the present invention comprises fiber reinforced plastics (FRP) and a coating layer formed on the surface of the fiber reinforced plastics. Specifically, the fiber-reinforced plastic and the coating layer may have a thickness ratio of 1:0.05 to 0.5, preferably 1:0.05 to 0.2, but are not limited thereto. Additionally, the fiber-reinforced plastic surface may mean that the coating layer is formed on one or both sides of the fiber-reinforced plastic, but preferably, the coating layer may be formed on all surfaces of the fiber-reinforced plastic. Meanwhile, the coating layer may include silicone resin, polyamide resin, stainless steel powder, and nickel-based alloy powder. If even one of these components is not included, there may be a problem in that it fails to satisfy both strength and excellent seawater corrosion resistance. The silicone resin may include a compound represented by the following chemical formula 1 and a compound represented by the following chemical formula 2. [Chemical Formula 1] In the above formula 1, R1 , R2 , R3 , R4 , R5 , R6 , R7 , R8 , and R9 are each independently -H, a C1 to C12 straight-chain alkyl group or a C3 to C12 branched alkyl group, preferably each independently is a C1 to C12 straight-chain alkyl group, and more preferably is a C1 to C3 straight-chain alkyl group. In addition, in the above Chemical Formula 1, B1 and B2 is each independently -CH2- , -CH2CH2- -CH2CH2CH2- , -CH2CH2CH2CH2CH2- , -CH2CH2CH2CH2CH2- , -CH2CH2CH2CH2CH2CH2- , -CH2CH2CH2CH2CH2CH2CH2- , or -CH2CH2CH2CH2CH2CH2CH2CH2CH2- , and preferably each independently is -CH2- , -CH2CH2- -CH2CH2CH2CH2- or -CH2CH2CH2CH2CH2- .​​​​​​​ In addition, in the above chemical formula 1, n is a rational numbe
