Composites, Fiberglass & Advanced Materials calculator
Autoclave Utilization Calculator
Use this calculator to compare productive cure time against available autoclave time, including loaded cure cycles, ramp, dwell, pressure hold, and monitored cool-down.
What this calculator does
- Calculate autoclave utilization for composite cure assets.
- tracking autoclave asset utilization
- The result shows autoclave utilization and gap to target.
Formula used
- Autoclave Utilization = productive autoclave cure hours ÷ available autoclave hours × 100
- Gap to target = Autoclave Utilization - target autoclave utilization
Inputs explained
- productive autoclave cure hours: Use loaded cure hours for qualified parts, panels, tools, or test articles during the period.
- available autoclave hours: Use scheduled autoclave availability after planned maintenance, calibration, and staffing limits.
- target autoclave utilization: Use the utilization target that preserves capacity for setup, maintenance, queue variability, and emergency cure loads.
How to use the result
- Use it to decide whether cure loading, shift coverage, maintenance windows, or capital capacity need adjustment.
- 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 autoclave utilization calculator for? Use this calculator to compare productive cure time against available autoclave time, including loaded cure cycles, ramp, dwell, pressure hold, and monitored cool-down.
- What information should I enter? Enter productive autoclave cure hours, available autoclave hours, and the target percentage from the control plan, customer specification, launch goal, or historical benchmark.
- What does the result tell me? The result shows autoclave utilization 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.
