The invention discloses a hoop and a forming method thereof, the hoop comprises a hoop belt with an elastic part, a first mounting part and a second mounting part, the first mounting part and the second mounting part are detachably connected through a connecting piece, and the elastic part, the first mounting part and the second mounting part are integrally formed by paving continuous long fibers and resin materials; the thickness of the
large deformation area of the elastic part is smaller than that of the small deformation area and / or the
large deformation area is provided with an annular groove. The invention provides a high-performance light-weight long-
fiber clamp which is used for fixing
aviation cables and pipelines, the clamp can independently adopt a strap and can also be used in cooperation with a rubber pad, the strap adopts a long-
fiber composite material strap to replace a
metal clamp strap, the product weight is reduced, the size is reduced, and the structural strength is guaranteed; by adopting the
modes of reducing structural design, combination of continuous long fibers and resin materials and the like, the
toughness of the strap is improved, the deformation elastic force is reduced, the hoop can be manually opened, and the problems of brittle failure and the like of the carbon
fiber strap are avoided.
