CFRP with High Hydrogen Gas Barrier Characteristics Using Inorganic Compound

研究了具有高氢气阻隔性的粘土膜材料的基本材料性能，如透气性和热膨胀系数，以及低温下强度等力学特性。建立了碳纤维增强塑料复合材料与粘土膜的复合制造工艺，为验证未来可重复使用空间运输系统的可行性，制造并测试了小型液氢原型罐。

The basic material properties such as hydrogen gas permeability and thermal expansion coefficient, and the mechanical characteristics such as strength under cryogenic temperature for the clay film materials with high hydrogen gas barrier characteristics, which consists of crystalline layered silicate with a flexible structure directionally oriented in one direction, have been studied. The composite and manufacturing technology of carbon fiber reinforced plastics compound with the clay film was established, and the small liquid hydrogen prototype tanks were manufactured and tested for the feasibility verification of future reusable space transportation system.
