| Outline of Final Research Achievements |
In this study, shear cutting mechanism of carbon fiber reinforced thermoplastic (CFRP) laminates was clarified through experiment and numerical analysis using a particle method. In addition, shear cutting conditions such as temperature, clearance and cutting blade geometry were optimized. The main result obtained from the above study is as follows: Burrs and matrix cracking are the dominant machining damages while delamination is little observed unlike thermosetting CFRP laminates. Shear cutting with low-machining damage is realized at around the glass transition temperature because shear load required for cutting is decreased and the toughness of the resin increases.
