A composite knitted mesh with neutral buoyancy and method of designing the same

Abstract

This invention discloses a composite woven net with neutral buoyancy control capability, belonging to the field of marine engineering and fishery equipment technology. The net is formed by weaving composite netting, which includes a first fiber component and a second fiber component. The density of the first fiber component is greater than that of water, while the density of the second fiber component is less than that of water. By adjusting the volume fraction of the first and second fiber components, the equivalent density of the composite netting is made to approximate the density of the sea area or water body in use. This method achieves neutral buoyancy of the netting in water through the combination of material densities, eliminating the need for additional floats or counterweights, resulting in a simpler structure. The netting experiences more balanced forces in water, helping to maintain structural stability and reducing the risk of deformation due to gravity and buoyancy. This invention has a simple structure, strong calculability, and can improve the morphological stability of the netting while reducing hydrodynamic resistance, making it suitable for applications such as fishing nets and underwater protective structures.
