In recent years, biomaterials have attracted attention in various fields in response to environmental problems. We pay attention to bamboo because it naturally decomposes and is characterized by its excellent elasticity and water absorption properties. We had proposed a bamboo-ice composite system as a substitute for the glass fiber reinforced plastics (GFRP) in electrical insulation systems at cryogenic temperatures. In this paper we will report the AC breakdown properties of a bamboo pulp-ice composite system at liquid nitrogen temperature. The bamboo pulp-ice composite system had AC breakdown strength comparable with GFRP and can be easily molded in various shapes. We consider that the bamboo pulp-ice composite system is promising as a substitute for the GFRP in the electrical insulating systems at cryogenic temperatures.
