Abstract
The invention relates to a hull of a vessel having characteristic surface properties, allowing an increase in surface runoff while benefiting from an inherent anti-fouling property and an original aesthetic appearance. Furthermore, the invention allows the incorporation of said outer composite envelope into the structure of the hull, thereby preventing delamination problems and inherently providing a vessel hull with the above-mentioned properties.
Claims22
A vessel hull comprising in an external envelope intended to be in contact with an outer liquid element, a metal powder characterized in that:
- said powder:
- contains more than 30% by mass of grains for which the diameter is greater than 45 μm and
- is partly in contact with said outer liquid element;
- the envelope has a thickness of less than 1 mm,
- and in that the powder comprises a copper powder with at least 60% by mass of copper based on the mass of powder.
A method for manufacturing a vessel hull comprising the following steps:
- a. providing a binder/metal powder mixture,
- b. depositing a layer of the mixture on a mold of a vessel hull;
- c. optionally adding fiber materials in said binder;
- d. hardening the binder/metal powder mixture for example by treatment with light, with heat or by adding a hardening agent optionally added to the mixture;
- e. optionally adding at least one additional structure layer and/or reinforcement layer on the first hardened layer in step c.;
- f. removing the vessel hull from the mold;
- characterized in that the metal powder contains more than 30% by mass of grains for which the diameter is greater than 45 μm.
