Composites, Fiberglass & Advanced Materials calculator
Delamination Risk Calculator
Use this calculator to rank delamination risk from poor surface prep, contamination, insufficient compaction, cure deviation, impact damage, or bondline weakness.
What this calculator does
- Estimate delamination risk priority for composite parts or bonded assemblies.
- prioritizing delamination prevention or containment actions
- The result ranks delamination risk using a severity × occurrence × detection score.
Formula used
- Delamination Risk = delamination severity score × delamination occurrence score × delamination detection difficulty score
Inputs explained
- delamination severity score: Rate structural, safety, customer, fatigue, repair, or scrap impact if delamination occurs.
- delamination occurrence score: Rate likelihood from process history, material condition, surface prep, cure logs, and inspection findings.
- delamination detection difficulty score: Rate how difficult it is to catch the defect before shipment using visual, tap test, ultrasound, NDI, or proof testing.
How to use the result
- Use it to prioritize NDI, surface prep controls, debulk rules, cure record review, or engineering containment.
- 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.
Common questions
- What is the delamination risk calculator for? Use this calculator to rank delamination risk from poor surface prep, contamination, insufficient compaction, cure deviation, impact damage, or bondline weakness.
- What information should I enter? Enter severity, occurrence, and detection scores using the same FMEA, process risk, or quality escalation scale used by your composites team.
- What does the result tell me? The result ranks delamination risk using a severity × occurrence × detection score.
- When is the result only an estimate? 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.
