The fatigue of C/C composites was investigated in bending and shear modes. In bending, a large stress ratio resulted in a decrease in strength; the decrease became small without water present. However, a large ratio led to a decrease in Young's modul

Research has been done with the aim of making a foam from benzylated wood. As a result we have found that it is possible to produce an expandable benzylated wood without adding any plasticizers or other polymers. We have also found that it is necessa
