Fiber plast #400
Fiber plast #400 by COSMO Co., Ltd. is a marine fiber-reinforced interior material used in ship interior construction or deck finishing. It is installed as part of an approved accommodation, service-space or interior surface system rather than as an isolated decorative product. Performance depends on the prepared substrate, compatible primers or adhesives, joint detailing and preservation of the approved material build-up. Damage around penetrations, weld seams, thresholds or heavily trafficked areas can expose the substrate and compromise appearance or system integrity. Neighboring products in the manufacturer's range may differ in density, thickness, finish, fire performance or application method; those distinctions are not defined in the supplied record. Repairs should therefore reproduce the approved system using the maker's documented components and application procedure.
Inspector Detail
▸
Common issues
- Gelcoat or surface-layer crazing from impact or thermal cycling
- UV degradation causing chalking or color fade on exposed installations
- Delamination between fiber-reinforced layers, often starting at cut edges or fixing points
- Moisture absorption at damaged edges leading to core softening
- Loss of fire-retardant additive performance after repeated heat exposure near galleys or machinery spaces
- Impact damage (dents, punctures) from cargo or maintenance work
Inspection checklist
- Verify installed material matches the DNV MED-approved product referenced in fire safety documentation
- Visual check for surface crazing, delamination, or panel deformation
- Tap test on suspect areas to check for internal delamination
- Check edges and fixing points for moisture ingress or softening
- Confirm no unapproved penetrations or cuts compromising fire division rating
- Check color/surface consistency for signs of UV or heat degradation
Service intervals
| Visual condition check | annual survey |
| Fire division integrity check (in way of A/B-class divisions) | at each Special Survey |
| Repair of damaged sections | as needed, using matching approved material |
Critical spares
- Matching panel sections of the same product type for repair
- Approved fixing hardware compatible with the fire rating
- Approved edge sealant/trim to prevent moisture ingress at cut edges
Safety
- Do not substitute unapproved materials that could downgrade the fire division rating
- Cutting/grinding of fiber-reinforced panel generates dust; use PPE appropriate to the material per manufacturer guidance
- Do not overcoat with unapproved products that add fuel load
Class survey
As with other interior lining materials, class checks that installed product matches the type-approved specification referenced in the fire safety construction certificate; field alterations that are not documented are a common survey finding.

Common failures & inspection points
Service & Maintenance
Inspect accessible surfaces for cracking, delamination, moisture damage, impact damage and failed edge details. Keep the substrate dry and correct leakage sources before cosmetic repair. Use only compatible repair materials and follow the maker's surface-preparation and curing instructions. Where the material forms part of an approved fire-rated or low-flame-spread arrangement, retain product identification and repair records for survey. Exact application thickness, curing conditions and repair limits must come from the manufacturer documentation and approval system.
