Abstract:

Aiming at the thermal deformation and thermodynamic problems of fiber-reinforced flexible film in service, polyimide (PI) fiber-reinforced polydimethylsiloxane (PDMS) flexible composite film was prepared with polyimide fiber as reinforcement and polydimethylsiloxane as matrix by scraper coating. The thermal stability of the composite membrane was studied using a thermogravimetric analyzer. The universal material tester and the thermomechanical analyzer were used to discuss the influence of the linear density and laying density of the oriented reinforced fiber on the mechanical properties and thermal expansion coefficient of the composite film. COMSOL finite element simulation was used to analyze the thermal expansion and deformation mechanism of fiber-oriented reinforced composite membrane. The results show that the rate of mass loss is only 1.22% at 300 ℃, indicating that the thermal stability of composite membrane below 300 ℃. With the increase of fiber layer density and linear density, the breaking strength and elastic modulus gradually increase and the thermal expansion coefficient gradually decreases, and both exhibit negative expansion characteristics, indicating that the orientation enhancement of polyimide fibers can effectively influence the dimensional stability of composite membrane materials. The correlation between the simulation and the experimental results is good, indicating that the model can be used to predict and optimize the thermal expansion coefficient of PI fiber-reinforced composite membranes.

Key words: polyimide fiber, thermal stability, thermal expansion coefficiency, mechanical property, finite element simulation, composite material, polydimethylsiloxane
