Abstract

The invention discloses a toughening FRP spiral connecting piece and a manufacturing method of the toughening FRP spiral connecting piece. The toughening FRP spiral connecting piece comprises a bolt, a nut and a gasket. The bolt comprises a bolt head and a threaded rod, wherein the bolt head and the threaded rod are connected into a whole, and external threads are arranged on the threaded rod. Internal threads are arranged on the nut. The external threads and the internal threads are matched with each other. The threaded rod is sleeved with the gasket. The nut is tightly screwed on the threaded rod. According to the method, an epoxy resin substrate serves as a main body, flexibilizers are then added, and resin adhesive materials, short fiber and fiber cloth are formed according to vacuum molding. Mechanical and semi-automatic molding forming is adopted for the FRP connecting piece, and therefore large-scale production can be achieved; the FRP connecting piece is used for connection of FRP components, and the overall corrosion-free function, the non-magnetic function, the electric insulation function, the vortex-loss-free function, the vortex-interference-free function and other functions are given into full play; when the FRP connecting piece is used, the large FRP component can be resolved into multiple small FRP parts, and the energy saving effect and the emission reduction effect are achieved.

Description

technical field [0001] The invention relates to an FRP connector, in particular to a toughened FRP spiral connector and a preparation method thereof. Background technique [0002] In order to improve structural durability, build a non-magnetic environment, and achieve electrical insulation, non-metallic materials have been widely used in engineering. Typical non-metallic materials include FRP (Fiber Reinforced Plastics, fiber reinforced plastics, also called FRP), ceramics, glass, etc. These engineering components composed of non-metallic materials often require connectors to be connected. If traditional metal connectors (metal bolts, rivets, pins and dovetails, etc.) are used, the overall function will be affected due to their own rust, magnetism and conductivity; therefore, corresponding non-metallic connectors are required. [0003] The FRP connector made of glass fiber, basalt fiber, carbon fiber or other high-strength fiber as the main material and resin as the auxili...
