INTEGRATED HELICOPTER SIDE SHELLS IN INFUSION TECHNOLOGY

Frank Weiland (Airbus Helicopters) Uwe Beier (Airbus Helicopters)

 

An innovative manufacturing routine for CFRP shell structures has been developed and demonstrated. It combines a VAP-infusion with a joining technology based on the interdiffusion of thermoplastic films with epoxies for cost and weight efficiency.

OUT-OF-PLANE DEFORMATION OF CARBON-FIBER-REINFORCED-POLYMER WITH LOCAL DAMAGE UNDER RAPID HEATING

Yasuhiro Fukuda (Tokyo University of Science) Jun Koyanagi (Tokyo University of Science) Akinori Yoshimura (Japan Aerospace Exploration Agency) Kenichi Hirai (IHI Aerospace Co., Ltd.) Satoru Yoneyama (Aoyama Gakuin University) Takuya Aoki (Japan Aerospace Exploration Agency) Toshio Ogasawara (Tokyo University of Agriculture and Technology)

 

In this study, we measured local out-of-plane deformation of CFRP ablator under rapid heating by using stereo DIC method. And we proposed analytical procedure in order to reveal the mechanism of thermal deformation of CFRP.
