Abstract
A composite marine structure comprises a marine substrate having adhered to at least a portion of its surface a layer of a water-permeable composite article comprising a non-woven fibrous web having entrapped therein active particulate to provide said marine substrate with protection against at least one of fouling and corrosion. Underwater surfaces such as ship hulls, buoys, docks, intake pipes, etc., can be protected against marine growth and corrosion by adhering thereto the composite sheet article of the invention.
Claims24
A composite marine structure comprising a marine substrate having adhered to at least a portion of its surface a layer of a water-permeable composite article comprising a non-woven fibrous web having entrapped therein particulate which is active toward at least one of marine fouling and corrosion, said article providing said marine structure with protection against at least one of fouling and corrosion.
A composite marine article comprising
- (a) a non-woven fibrous web,
- (b) particulate, which is active toward at least one of marine fouling and corrosion, entrapped within said web, and
- (c) a dual-sided tape attached to at least a portion of one surface of said web.
A composite marine article comprising
- (a) a non-woven fibrous web,
- (b) particulate, which is active toward at least one of marine fouling and corrosion, entrapped within said web, and
- (c) a liner attached to at least a portion of one surface of said web.
A method of interfering with at least one of
- 1) accumulation of marine growth on, and
- 2) corrosion of
- a marine structure comprising the step of allowing fresh or sea water to come into contact with a composite sheet article which is attached to a marine substrate, said composite sheet article comprising a porous, non-woven, fibrous web with active particulate entrapped therein, said active particulate providing at least one of fouling and corrosion protection to said marine structure.
