| Outline of Final Research Achievements |
This investigation aims at realizing the Ultra-lightweight structures by forming CFRPs, which are composed of thermosetting resin and continuous carbon fibers, and the high-speed manufacturing of CFRP sheet. The application of CFRP-metal-based ultra-lightweight structures will have a marked increase in vehicles and industrial machines. High-speed manufacturing of CFRP sheets, forming of CFRP sheets and hybrid structures composed by metal sheet and CFRP were investigated to reach above goals.
Continuous production of thermosetting CFRP sheets were experimentally tried by using rolling mill and furnace. The quality of manufactured sheet is slightly inferior to those manufactured by using autoclave: however, the sheet with void fraction less than 3% were successfully manufactured. Metal face sheet with three-dimensional CFRTP core hybrid structure is newly proposed. This hybrid structure can change and optimize macrostructure to attain expected formability and flexural strength.
