Study on Mechanical Properties of the Tubular Textile Composite Using Finite Element Analysis
The tubular textile composite material as the liner is inversed in the pipeline by gas or water pressure, and then the damaged pipeline can be rehabilitated. During inversion, because of the inversion pressure, the tubular textile composite material must endure the complicated stress and strain. Adopting the Finite Element Analysis, the paper analyzed the stress and strain of the tubular textile composite during inversion, and the finite element simulation data compared with test data. The results show that the stress and strain in head of the tubular textile composite material during inversion is instability, where the stress is concentrative, so the head of the tubular textile composite material is easy to break.
