After issues of applying LCA concept on CFRP are mentioned, inventory data of carbon fiber are shown. These are the first standard data in carbon fiber industries. Finally, sensitivity analysis are applied.
Sensitivity analysis is an effective method to evaluate uncertainty of inventory analysis.
It is also useful to determine which process should be improved to reduces environmental impact. The importance of the data is used for determining which data should be revised and which data we can ignore or use substitute data. Based on formulation using partial differential, sensitivity analysis are carried out with low calculation-cost in high accuracy. Calculation examples for epoxy resin production process and prepreg production process are presented.
