Abstract: The connection reliability of the envelope material is important to the stability of the aerostat. In order to ensure the reliability of the connected material, the thermal bonding test of two kinds of envelope materials with different surface densities and matching materials was conducted at different processing parameters. Under the premise that the thermal bonding stripping strength meets the requirements of the index, the performance of thermal bonding part is further evaluated by high temperature creep test. The results show that the thermal bonding stripping strength of the envelope material gradually increases with the heat sealing time. The envelope material with higher surface density has higher tensile strength and stripping strength. The thermal bonding part with qualified stripping strength may delaminate after high temperature creep test, and incomplete melting of the adhesive layer is the main reason for the delamination of the samples.

Key words: aerostat, high-temperature creep, envelope material, connection reliability, thermal bonding stripping
