Aiming at development of composite structures applicable to next-generation transports, a TMU-JAXA joint research was started in 2008 on advanced composite technologies such as the structural health monitoring system for damage detection and the stitching composite technology to suppress delaminarization of composite materials which is the most serious problem for the composite structures.

In order to demonstrate applicability of structural health monitoring technology to damage detection of composite wing, a rotor blade with optical fibers embedded is manufactured. In addition, to confirm validity of the stitching technology in actual application to main wing structures, a model wing is made with stitched composite materials and its mechanical advantage is examined.
