Design and Qualification of a Advanced Hybrid Filament-Wound Composite Pressure Vessel for Aircraft Application

Abstract

This paper describes a composite pressure vessel(COPV) development program which have been finished by Lanzhou Institute of Physics (LIP). In order to dramatically improve reliability and safety of COPV applied in military aircraft, this COPV(L376-COPV) design relies partly on the heritage of mature technologies and was developed in combination with existing and new technologies, Unlike traditional COPV, the impact resistant capability from high energy bullet of L376-COPV is improved greatly by liner material heart treatment and T800/K49 fiber hybrids over-wrap. L376-COPV design, analysis, manufacturing, testing and results was introduced.
