Problems solved by technology

[0002] The existing fiber (such as carbon fiber, glass fiber, acicular wollastonite) reinforced composite hollow ball, due to the high density of the wall material (1500–3000 kg / m 3 ), which limits the strength / density ratio of the composite hollow sphere itself, such as figure 1 , figure 2 or image 3 As shown, in the case of the same density, the upper limit of its strength is carbon fiber composite hollow sphere, and the lower limit is glass fiber or wollastonite composite hollow sphere
The performance range of this material is difficult to meet the high requirements in some marine engineering (that is, lower density at high strength, or higher strength at low density) applications (such as deep-sea mining, buoyancy blocks for ultra-deep water submersibles, etc.)
[0003] At the same time, after the traditional hollow ball manufacturing process forms a finished product, due to defects in the production process (there is no monitoring and supervision of the product in the manufacturing process), if the diameter, wall thickness, density and hydrostatic pressure of the hollow ball do not meet the expected If the set value (the parameter index provided by the customer or the actual production parameter index), the finished product will be scrapped, which will lead to a continuous increase in the scrap rate and a continuous decrease in work efficiency.

Abstract

The invention relates to the technical field of hollow balls applied in ocean engineering (such as drilling riser buoyancy modules, distributed buoyancy modules, deep-sea mining and ultra-deep water submersible buoyancy modules), in particular to a hollow ball with the ball wall made from a composite material and a layer-by-layer coating method for manufacturing the hollow ball. The hollow ball comprises a ball wall layer which is filled with hollow glass microbeads. The hollow ball is simple in structure and high in practicability.
