AI Technical Summary
The existing surf tail rudder production process results in heavier tail rudder, low production yield and inconvenient operation, making it difficult to meet the lightweight needs.
The tail rudder is made of prepreg composite fiber material, combined with the design of nylon tube and air nozzle, and the strength and flexibility of the tail rudder are increased through hollow design and multiple angles and size adjustments of the composite material.
The ultra-light design of the tail rudder is realized, which reduces the weight of the surfboard, increases buoyancy and portability, while improving the strength and applicability of the tail rudder.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of composite material products and sports goods, in particular to an ultralight surfing tail rudder. Background Art
[0002] Surfing is a water sport in which athletes stand on a surfboard or use a belly board, kneeling board, inflatable rubber mat, rowing boat, kayak, etc. to control the waves. Regardless of the equipment used, athletes must have high skills and balance ability, and be good at swimming long distances in wind and waves. The tail fin of a surfboard is commonly known as the tail fin. It is an accessory installed at the tail of a surfboard and plays a decisive role in the direction, operating feel, response speed, and change of direction.
[0003] At present, the production of tail rudders is mainly based on RTM molding process. The main principle of RTM process is to lay the reinforcement material preform designed according to the performance and structural requirements in the mold cavity (the mold cavity needs to be pre-made into a specific size), and inject the special resin system into the closed mold cavity by injection equipment or vacuum method within a certain pressure range, and form it through the infiltration and curing of the resin and the reinforcement. The mold has peripheral sealing and fastening as well as injection and exhaust systems to ensure smooth flow of resin and exhaust all gases in the mold cavity and thoroughly infiltrate the fibers; at the same time, it has a heating system that can heat and cure to form composite material components. The tail rudder made by this method is relatively heavy, the yield rate in the production process is not high, and it is not easy to operate. Now people are constantly working hard to pursue lightweight. Utility Model Content
[0004] The utility model aims to provide an ultralight surfing tail rudder to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] An ultralight surfing tail rudder comprises a composite material, a nylon tube and an air nozzle. The composite material is a pre-impregnated composite fiber material. The size of each layer of the composite material, the angle of the fiber filaments and the fiber mass per unit area of the pre-impregnated material are different. At least half of the layers of the composite material wrap around the wheel edge. U-shaped wheel edge support ribs are provided along the inner edge of the wheel edge and U-shaped support ribs are provided in the middle. The nylon tube is installed in the wheel edge support rib. The nylon tube is a high-temperature resistant tube with openings at both ends. Air nozzles are installed in both ends of the tube openings.
[0007] As a further solution of the utility model: the shape of the wheel side support rib is similar to that of the tail rudder, and the outer surface of the inner sleeve nylon tube is coated with a resin anti-sticking agent.
[0008] As a further solution of the utility model: the pipe mouth of the nylon tube is reduced to fix the air nozzle, and the outer surface is covered with a composite material.
[0009] As a further solution of the present utility model: The composite material includes a material layer around the wheel rim, with serrations provided on the periphery and multiple serrations provided at the rounded corners.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: It has a hollow design, so the weight of the rudder is lighter; it reduces the weight of the entire surfboard, increases buoyancy and is more convenient to carry. The wheel rim support ribs and the support ribs are used to support the vacuum, increasing the strength. The composite material has various angles and sizes to adjust the strength of the rudder, suitable for different people. At the same time, prepreg composite materials are used, and the quality of the thermoformed products is stable, and various appearances can be made on the surface. BRIEF DESCRIPTION OF THE DRAWINGS
