    Improvement of Development Process for Thermosetting Composites Parts by Improving Accuracy of Curing Analysis


    Light-weight and high-strength thermosetting composite materials have been increasingly applied mainly to aircraft applications. However, if the temperature conditions during the curing of the composite material are not correct, the mechanical properties can deteriorate, so the setting of the correct curing conditions for each part configuration is necessary. Generally, in the case of composite parts for aircraft, the curing conditions were set through about 5 to 10 part temperature measurement tests, and the reduction of the test cost was a challenge. Therefore, to improve the curing conditions setting process, curing analysis that can predict composite part temperature was applied and its accuracy was enhanced.
