Abstract
The paper introduces the state-of-the- art of Fiber Reinforced Plastic (FRP) vessels, especially high pressure gas containers in Japan, and discusses the pros and cons of the FRP vessels to steel vessels. Emphasis is laid on compressed natural gas (CNG) containers aboard automobile vehicles. The outline of the standards applied to the CNG containers is described briefly. Low temperature containers used for liquefied natural gas aboard vehicles are also mentioned.
