LESSONS LEARNED IN FULL COMPOSITE AERO-STRUCTURES DEVELOPMENT IN JAPAN

T. Ishikawa
JAXA, Japan

Keywords: fabric composite, buckling, t-stiffener, compression after impact, delamination

The research work accomplished by the author, the recipient of ICAS Award for Innovation in Aeronautics, Dr. Takashi Ishikawa, is briefly reviewed. His early research work was inspired mainly by the development of the full composites horizontal empennage model for the experimental STOL aircraft, named “Asuka” and developed in Japan in early 80’s. From those days, the most widely applied composites were carbon fiber reinforced plastics: CFRP. His later research accomplishments related to the most serious drawback of CFRP, the mechanism of degradation in compression after impact (CAI) strengths is also reviewed. His final achievement is the one of the recent topics: research related to the low cost manufacturing technology, so-called vacuum assisted resin transfer molding: VaRTM. Typical examples of his recent work will be shown in ICAS 2012 presentations.
