  • The launching tube is an important part of the rocket system. In the process of longterm storage, aging phenomena inevitably occur under various stress and environment factors, with important influences on the system reliability. The glass fibre reinforced plastic (GFRP) launching tube was studied through thermomechanical tests of the oneway GFRP slabs. The tests and measurements gave the basic thermodynamic performances of the oneway GFRP slab materials, including the basic mechanical properties after accelerated aging. The mechanical model for the GFRP launching tube was constructed and the thermodynamic characteristics of the GFRP launching tube under loads were analyzed. Then the creep models for the GFRP launching tubes were established, that is, the composite laminate model and the anisotropic model. With the structural model, the material parameters for the longterm performance analysis of nonmetallic directional tubes were provided.
