Method for detecting creep characteristics of flaky composite material

The invention relates to the technical field of flaky composite material detection, and discloses a flaky composite material creep characteristic detection method, which comprises a measurement principle, a measurement device and a detection step, the measurement principle is as follows: firstly, the flaky composite material is regarded as a current channel, and when constant pressure stress is applied to the channel, the current channel is determined to be the creep characteristic of the flaky composite material; the composite material has a creep phenomenon, the axial size is decreased, the radial size is increased, particle gaps in a current channel are decreased, contact points are increased, and consequently current is increased, and resistance is decreased. By arranging a lifting table, a pressure head, a displacement sensor, a composite material gasket, an electrode plate, a heating type objective table and a pressure sensor, the resistance, temperature and strain data of the material in the creep defo
