Composites, Fiberglass & Advanced Materials calculator
Composite Yield Calculator
Use this calculator to measure how many composite parts pass layup, cure, trim, NDI, dimensional, visual, or final inspection without scrap or rework.
What this calculator does
- Calculate first-pass yield for composite parts, panels, coupons, or assemblies.
- tracking first-pass yield for composite manufacturing
- The result shows actual first-pass yield and gap to target.
Formula used
- Composite Yield = composite parts passing first time ÷ composite parts inspected or produced × 100
- Gap to target = Composite Yield - target composite first-pass yield
Inputs explained
- composite parts passing first time: Count parts, panels, blades, hulls, coupons, or assemblies accepted without repair, rework, or concession.
- composite parts inspected or produced: Use the total parts built or inspected in the same part family and period.
- target composite first-pass yield: Use the customer, launch, control-plan, or historical yield target.
How to use the result
- Use it to decide whether process containment, training, tool repair, or material corrective action is needed.
- 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 composite yield calculator for? Use this calculator to measure how many composite parts pass layup, cure, trim, NDI, dimensional, visual, or final inspection without scrap or rework.
- What information should I enter? Enter composite parts passing first time, composite parts inspected or produced, and the target percentage from the control plan, customer specification, launch goal, or historical benchmark.
- What does the result tell me? The result shows actual first-pass yield and gap to target.
- 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.
