| Outline of Final Research Achievements |
This project provides the trial development of a super fiber-reinforced ice (FRI) with the compressing strength exceeding 100 MPa, that can be utilized for the fabrication of an one-time disposable die. Waste-paper-pulp fibers, nano-cellulose fibers, carbon fibers, glass fibers and aramid fibers were examined for the purpose. With the dynamic compression tests, it is revealed that the aramid fibers are the most effective for high compression strength, and waste-paper pulp fibers were the second best. Carbon fibers were next, and nano-cellulose fibers were the most ineffective. In the compression text with the FRI with an aramid fiber, it displayed that its nominal compression-strength exceeded 100 MPa and fall of the compression load caused by the fracture of the specimen was not observed; however its true compression-strength was about 30 MPa on the other hand. It is thought that the fiber bonding strength with the ice matrix gave the limit of the true strength of the composite.
