Scope of Main Business Activities

コンテンツ

Our Research & Development Center conducts contracted tests and research, for contributing to the enhancement of safety in the areas of high pressure gas and liquefied petroleum gas.
Among the research contracted by the government and other organizations are design of fiber-reinforced plastic (FRP) composite containers, study on materials used with hydrogen fuel containers and valves for Hydrogen Fuel Cell Vehicles (HFCV), and development of microcomputer meters for LP gas. The research results have been used as basic data for preparing exemplified standards by the government.

Comprehensive support for design and development of pressure containers through tests contracted by private-sector entities

Drawing on the knowledge accumulated in research and development of FRP composite containers for over 30 years since 1985, our Research & Development Center has conducted tests and research contracted by private-sector entities, including internal pressure tests using boosters that are among the largest in Japan, as well as various material tests and structural analysis by finite element methods (FEM). These tests have contributed toward the development of new technologies and products.
We have established an organization capable of comprehensive design and development support for FRP composite containers, through our experiences in structural analysis of FRP composite containers by FEM, tensile and fatigue tests on various materials, cycle tests using internal pressure test equipment, and verification experiments for bursting, pressure proof, and other types of tests. We are capable of handling various tasks from acquisition of data on basic characteristics of FRP materials to consultations regarding type approval tests and batch tests.
