Design of the solar panel frame of the spacecraft by 3D printing with composite materials

Annotation This article examines the study of strength properties of polymer composite material, based on 3D-printed frame produced by FDM technology. The printing material is ABS plastic (acrylonitrile butadiene styrene). After the printing samples frames were soaked in pure epoxy resin with various hardeners. Subsequent curing went in two modes. After that, tensile tests were performed. The strength of impregnated, non-impregnated (clean frame) samples and samples made of pure resin was compared. Tests have shown that the strength of impregnated samples exceeds the strength of non-impregnated ones, but obtained strength value of impregnated samples were far from the expected theoretical values. It was found that low strength is associated with poor quality of the impregnation.

This work is devoted to the study of tribotechanical properties of 3D printed samples from ABS plastic. The results of determining the coefficient of friction and mass wear of the samples obtained by 3D-printing with different printing heights during the friction testing on machine II 5018 are presented. It is shown that in order to reduce the coefficient of friction and mass wear of the ABS plastic specimen, it is recommended to produce specimens with a higher print height. 3D printed parts with 0.3 mm layer height have shown the best results because of greater layer adhesion.

Annotation. The paper discusses a method of increasing the strength of 3D-printed structures made by the fused deposition modelling process, which consists in vacuum impregnation of printed products in a compound based on epoxy resin. Studied the number of pores in samples obtained by this method depending on the percentage of 3D printing filling and direction of layers relative to the axis of the samples. The porosity of the samples was determined by comparing the theoretical ideal density with the experimental value determined using the hydrostatic weighing method. As a result, it was found that the porosity of the samples lays in the range from 17 to 18.5%. It was also found that with increasing percentage of filling the porosity of the samples increases. It has been suggested that this dependence is associated with a complication of the processes of air release from samples during the impregnation.
