Composite Materials and Structures Development in FHI for High-Speed Civil Transport

Development of a light structure with composite materials is one of the key technologies to realize an economic HSCT(High Speed Civil Transport).

FHI(Fuji Heavy Industries) has continued to investigate heat resistance polymer (thermoplastic polyimide) matrix composite materials and their application to aircraft structures since 1987 jointly with MTC (Mitsui Toatsu Chemicals), Inc[1, 2 and 3].

FHI has started Ti Honeycomb Sandwich Panel Development and Fiber/Metal Laminate Development for high temperature aircraft structures.

The status of above studies FHI has ever investigated and the concerns for future studies are summarized herein.
