Method for protecting a profile structural part of an aircraft against mechanical wear and/or mechanical impact

A method for manufacturing a protected profile structural part of a fuselage of an aircraft, the method comprising:

• a) providing a finished structural profile part, the finished structural profile part having a surface to be protected;
• b) preparing a sealant mold separate from the finished structural profile part, wherein the sealant mold includes a mold cavity, wherein the mold cavity has a cross-section that matches a portion of the profile structural part on which the surface to be protected is disposed, such that a molded part made with the sealant mold can be attached to the portion of the profile structural part;
• c) injecting the mold cavity with uncured wet sealant until a squeeze out of uncured wet sealant indicates that the uncured wet sealant has fully filled the mold cavity, curing or letting cure the uncured wet sealant into a cured sealant member within the mold cavity after the uncured wet sealant has been injected into the mold cavity, and removing the cured sealant member from the sealant mold after the uncured wet sealant has been cured into the cured sealant member;
• and
• d) attaching the cured sealant member to the finished structural profile part in a non-movable manner so as to form a protective liner on the surface to be protected and to generate the protected profile structural part.
