Abstract

The research was focused on modification of the polyimide binding material SP-97s. The character of transformations in the binder, which contents modifying additives of different types, was studied on the stage of material forming. The optimum amount of modifiers was determined and effectiveness of each of them with the purpose to decrease curing temperature of binder down to 170°C was estimated taking into account the properties of fiberglass plastics. The composition of modifying binder was established, polyimide fiberglass plastic STP-97K was developed and its properties were studied. It was demonstrated that lowering of the curing temperature does not cause a significant change of properties of the material in different operational conditions.
