Thermoplastic composites have excellent mechanical properties and are ideal structure materials for reusable launch vehicles. The research of mechanical behavior has attracted tremendous attention in the fields of solid mechanics and material sciences worldwide. In this paper, the prediction methods of macro-mechanical properties, plastic constitutive relations, damage and fracture mechanical behavior, and analysis of mechanical behavior of typical structures of thermoplastic composite are reviewed. At present, many important key problems need to be solved, such as accurate prediction of macroscopic mechanical properties of thermoplastic composites, reasonable characterization of elastoplastic damage mechanical behavior of thermoplastic composites, and simulation of mechanical behavior of thermoplastic composite structures in complex multi-field coupling environment such as aerodynamic heating, overload and impact. Future research can be carried out from the following aspects: (1) to establish a unified macro and micro mechanical property prediction model of thermoplastic composites, (2) carry out macro and meso-mechanical analysis of carbon nanotubes reinforced thermoplastic composites, (3) study the mechanical behavior of thermoplastic composites under typical multifield coupling environment such as thermodynamic coupling, (4) carry out structure-level experimental research on thermoplastic composites.
