CLAIMS

1. A method for producing a PBO fiber with increased resistance against UV-caused degradation, the method comprising providing a coating on the PBO fibers, the coat ing comprising graphene oxide cross-linked by polymerization with glutaraldehyde and resorcinol.

2. The method of claim 1, wherein the coating comprises GO dispersed in deionized water and treated with resorcinol and glutaraldehyde with a mM-ratio of 1 :2.

3. The method of claim 2, wherein the coating comprises GO dispersed in deionized water and treated with a solution containing 11 mM resorcinol and 22mM glutaralde hyde.

4. A PBO fiber coated with graphene-oxide cross-linked with glutaraldehyde and res orcinol.

5. A laminate material comprising a reinforcing fiber layer, the reinforcing fiber layer comprising PBO fibers coated with graphene-oxide cross-linked with glutaraldehyde and resorcinol.

6. An airship hull comprising a fiber layer, the fiber layer comprising PBO fibers coated with graphene-oxide that is cross-linked with glutaraldehyde and resorcinol.

7. A lighter-than-air vehicle comprising a hull, the hull comprising a laminate materi al as a gas barrier and load-bearing structure, the laminate material comprising a rein forcing fiber layer, the reinforcing fiber layer comprising PBO fibers coated with gra phene-oxide cross-linked with glutaraldehyde and resorcinol.

8. Use of PBO fibers coated with graphene-oxide cross-linked with glutaraldehyde and resorcinol for reducing degradation of PBO fibers caused by exposure to light, UV radiation or chemical reactions.
