Composites, Fiberglass & Advanced Materials calculator
Composite Repair Cost Calculator
Use this calculator to cost sanding, scarf repair, patch layup, adhesive bonding, gelcoat repair, cure, inspection, and documentation for nonconforming parts.
What this calculator does
- Estimate repair cost for composite defects, damage, delamination, voids, or cosmetic issues.
- estimating rework or repair exposure for composite parts
- The result estimates total repair cost for the selected composite defect population.
Formula used
- Variable composite repair cost = composite repairs required × repair cost per composite defect × repair scope included
- Total composite repair cost = variable composite repair cost + fixed repair setup and quality cost
Inputs explained
- composite repairs required: Count defect repairs, MRB dispositions, scarf patches, gelcoat repairs, or rework orders in scope.
- repair cost per composite defect: Include technician labor, materials, consumables, cure time, inspection, NDI, and documentation.
- repair scope included: Use 100% for full repair scope or less for cosmetic, structural, field, or in-process repairs only.
- fixed repair setup and quality cost: Include engineering disposition, fixtures, NDI setup, travel, or special cure support.
How to use the result
- Use it for MRB reviews, warranty exposure, root-cause prioritization, and quote allowances for difficult parts.
- Treat the result as a planning estimate until it is checked against the approved laminate schedule, material datasheets, ply books, resin batch records, tool condition, cure logs, inspection results, customer specification, and actual shop observations for the same part family and process.
