Embodiment Construction

[0063] Such as figure 1 , 2 As shown, the composite keel that resists bending and torsional compound deformation proposed by the present invention includes a keel main body 11 and a fiber groove profile 12, and at least one layer of fiber groove profile 12 is bonded to one of the top or bottom surfaces of the keel main body 11. The fiber channel profile 12 can be pasted on both the top surface and the bottom surface of the keel main body 11 . The main body 11 of the keel can be straight, or one end is upturned, or both ends are upturned.

[0064] The first embodiment is a preferred embodiment of the present invention, such as figure 1 , 2 As shown, in this embodiment, one end of the keel main body 11 is tilted upwards, and a layer of fiber groove profile 12 is provided on the top and bottom surfaces of the keel main body 11 , and the fiber groove profile 12 fits the curved surface of the keel main body 11 . The keel main body 11 can be made of high-strength materials suc...

Abstract

The invention discloses a bending and torsional composite deformation resistant combined keel and a surfing board. The bending and torsional composite deformation resistant combined keel comprises a keel main body and at least one layer of fiber groove profile arranged on the top surface and / or the bottom surface of the keel main body. According to the bending and torsional composite deformation resistant combined keel, by integrally connecting the U-shaped fiber groove profile with the keel main body, the comprehensive strength of the keep resisting bending and torsional composite deformationis enhanced, and moreover, the elasticity is good, the surfing board is not prone to being broken, and the safety of the surfing board is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of surfboards, in particular to a combined keel resistant to compound deformation of bending and torsion and a surfboard with the combined keel. Background technique [0002] Surfboards are leisure sports equipment used for surfing. Users can surf on the surfboards in a standing manner. Therefore, it is necessary to strengthen the strength of the surfboards to prevent breakage. Surfboards can be divided into two categories according to the existing production process: glass fiber surfboards and non-glass fiber surfboards. [0003] The first type of fiberglass surfboard is that a hard glass fiber resin layer is cemented on the bottom and face of the foam core board. The surface of this surfboard is hard and is generally called a hard board. Common foam core materials include expanded low-density polystyrene (EPS) and expanded polyurethane (PU). Some anti-bending materials can be further added into the foam ...
