High-performance fiber ropes possess excellent mechanical properties and design flexibility, making them widely applicable in spacecraft deployable structures such as space tethers, mesh deployable antennas, and thermal knife hold-down and release mechanisms. Substantial progress has been made in the study of creep and stress relaxation behaviors of fiber ropes, providing critical support for their use in inflatable space structures like space habitats. However, several key issues remain to be addressed:

1. The essence of creep and stress relaxation in fiber ropes lies in the alteration of the molecular conformation of the fiber material under load. Due to the material's unique molecular structure, different viscoelastic responses are exhibited. There is a need for systematic research on the creep and stress relaxation behaviors of high-performance fibers under multi-factor coupling conditions such as load, temperature, humidity, vacuum, radiation, and atomic oxygen.

2. Fiber ropes are multi-level fiber assemblies. Currently, the relationship between factors such as yarn twisting, braided structure, and the creep and stress relaxation behaviors of fiber ropes has not been established. It is necessary to develop theoretical models and conduct extensive experiments to analyze these relationships.

3. The connection efficiency between fiber ropes and other components requires optimization and improvement, particularly for pin-and-cone connection methods. The relationship between the connection strength of fiber rope assemblies and the braided structure needs further exploration.
