Abstract: Static and fatigue test for full-scale composite fuselage barrels is firstly planed as a large composite component test. In order to finish the test successfully and accumulate relevant technical experience, the current status of static/fatigue test technology for civil aircraft and large transport aircraft is presented. A special boundary simulation of composite fuselage with large diameter and heavy load, brace strut-differential combined statically determinate restraint system and an integrated loading system of static/fatigue test had been studied and applied. These above-mentioned new technologies had been successfully applied on the test,which have accelerated test implementation speed, and improved the safety and reliability of the test. The results showed that the technologies are safe, reliable and efficient. The test requirements and expected objectives have been achieved, and a complete and effective test technology system for a large full-scale composite fuselage barrels test is formed, which provides a good foundation for the application of composite materials for wide body aircraft fuselage.

Key words: composite fuselage, static and fatigue test, boundary simulation, statically determinate restraint system, integrated loading system
