Abstract

Abstract: This article studies a new type of composite material structure for airship envelopes, which consists of a polyurethane matrix and a plain weave nylon reinforcement. Based on the Ogden constitutive model, the mechanical properties of the envelope material in the warp and weft directions are fitted. The tear performance of the envelope material under high and low temperature conditions was studied by conducting tear tests at -5 ℃, 80 ℃, and room temperature. The tear performance of the envelope material with a central prefabricated crack was simulated using the extended finite element method (XFEM). Based on the experimental and simulation results, the impact of prefabricated cracks on the mechanical properties of the envelope material at different temperatures was systematically evaluated, and the crack propagation process and path were further analyzed. The simulation results were in good agreement with the experimental results. The results show that when the temperature changes from -5 ℃ to 80 ℃, the maximum tear strength decreases by about 40% and the tear strain increases by about 28%. Therefore, it is necessary to pay attention to the tear characteristics of the envelope material at high temperature. The extended finite element method used in this paper has strong applicability for simulating the tear behavior of airship envelope materials.
