Title: BUOYANCY MEMBER FOR FLOATING ON A LIQUID
Abstract:
The invention relates to a buoyancy member for floating on a liquid having the density dO comprising a member core (1), comprising a member shell (2) surrounding the member core (1) in a liquid-tight manner, and having an overall density d which is lower than the density dO of the liquid, wherein the member core (1) is made of a material of the density d1 and the member shell (2) is made of a material of the density d2, wherein an outer surface (3) of the member shell (2) surrounds the total volume which determines the buoyancy of the buoyancy member. The buoyancy member is characterized in that the material of the density d1 of the member core (1) contains at least one injection-molded and optionally foamed plastic and completely fills a closed hollow space (4) formed by the member shell (2), and the material of the density d2 of the member shell (2) preferably contains at least one pore-free or closed-pore plastic which is preferably injection-molded.
