Delamination has been the root of all evil for CFRTS. It is well known to cause the drastic reduction of compressive strength, accordingly the design strength is restricted and careful NDT is necessary in operating. Furthermore, we hesitate to make a hole for fastening to avoid stress concentration and delamination, therefore manufacturing facilities for near net shape molding become large and expensive. However, developing CFRTP in this project is, in contrast, insensitive to stress concentration, and the delamination does not occur in its fracture process. The tough nature of this material not only brings large energy absorption capacity but also provides more flexible manufacturing methods of composite structure than before. The goals of this project concerning production cycle time and mechanical properties will be achieved by further improvement of developing technologies. In addition, if the constraint of the cycle time can be released, these new properties of developing CFRTP will be able to give new possibilities of both designs and manufacturing methods to composite structure. Consequently, in the next stage, we would like to challenge to create a new composite structural design to satisfy any demanded combination of structural properties and manufacturing cycle time. For example, we will pursue the fastest cycle time to manufacture CFRTP automotive body whose gross weight reduction ratio is sixty percent of current passenger automobile. Furthermore, the social role of automobile and its new functions have been discussed recently, such as pedestrian safety, support tool for elder, etc. We believe that the developing CFRTP will contribute to realize and create such kinds of new concepts and functions of future automobile.
