Abstract

The invention discloses a high-temperature-resistant bionic driver as well as a preparation method, a preparation system and a test method thereof. The preparation method comprises the following steps: twisting polymer fibers under a first temperature condition until the polymer fibers completely form a spiral structure; and annealing the twisted polymer fiber under a second temperature condition to prepare the high-temperature-resistant bionic driver, wherein the first temperature condition is near the transition temperature of the polymer fiber, and the second temperature is lower than the first temperature. According to the preparation method of the high-temperature-resistant bionic driver provided by the invention, due to the excellent high-temperature resistance and mechanical properties of the special fibers and the carbon nanotube narrow bands, the prepared bionic driver has good heat resistance and stability, the use temperature upper limit of an existing polymer-based fibrous bionic driver is broken through, the application of the bionic driver in extreme environments such as aerospace and the like can be explored.

Description

Problems solved by technology

However, in some special application scenarios of the driver, such as aerospace exploration, industrial metallurgy and other high-temperature conditions, the ambient temperature can reach 400-500 ° C or even higher, including traditional motors, shape memory alloys, ion elastomers, etc. Some drivers cannot withstand such a high ambient temperature, and the existing drivers that can work at high temperatures are very rare

[0004] Existing bionic actuators have the disadvantages of low heat-resistant temperature and narrow operating temperature range, which cannot meet the requirements of use in extreme high-temperature environments, and the traditional thermal drive method uses heat guns, light heat, etc. as heat sources, and there is a heat exchange process limited and slow heat transfer rate, and the existing ultra-high temperature drivers such as pure carbon nanotube fibers and film boron nitride, etc., the driving performance is limited, and the existing technology is less researched on bionic drivers at high temperature Dynamic drive performance and cycle stability in ambient conditions

[0005] Although the driving temperature of pure carbon nanotube fibers and film-like boron nitride drivers that have appeared in recent years exceeds 2000K, the driving performance is limited, and there is also a lack of research on driving performance in high-temperature environments.
