Development and research of carbon plastics with shape memory effect, which have the required thermomechanical characteristics and inversion properties

The purpose of the study is to develop and investigate polymeric composite materials (carbon plastics) with thermally stimulated shape memory effect (TS SME) for an ultralight controlled, reversibly transforming structural member of picosatellites solar cells. Research aims on the development of a polymer matrix with TS SME and high glass transition temperature in the cured state (Tg over 140°C) and reinforced laminated carbon plastics on its basis. A polyetherurethane-epoxy (PEU-E) composition cured by diaminodiphenylmethane was developed and kinetics of its curing was investigated by the dielectric analysis method (DEA) for selecting of carbon plastics compression modes. The effect of the composition curing conditions on its Tg was studied and the reversible temperature of the TS SME development by the dynamic mechanical analysis (DMA) method of was determined. The last stage of the work was the TS SME realization studies – force and deployment angle kinetics dependence on the number of carbon fabric layers and its volume content in reinforced laminated carbon plastics specimen.
