| Outline of Final Research Achievements |
Spider silk consists of cylindrical filaments. Even though filaments in the aggregate of a number of filaments are ideally aligned in parallel and packed together, each filament contacts linearly. Since the actual aggregate contains openings among filaments, however, the applied stress is much lower than that of monofilament. In order to make clear such a problem, the author examined a mechanism for increasing the face contact between filaments. He succeeded in increasing the ratio of face contact by applying the pressure in the direction perpendicular to the filament axis. As a result, the applied stress of aggregate increased drastically. Especially, it was found that the elastic modulus and the applied pressure in the direction perpendicular to the filament axis should be considered for deforming filaments and then increasing the face contact between filaments.
