A Study of the Influence of Molding Technology on the Mechanical and Elastic Properties of Basalt Plastics Based on Epoxy Binder

Results of studies of the strength and elasticity moduli of basalt plastics during their tests for tension, bending, compression, interlayer shear, and crack resistance depending on the technology of their manufacture are presented. Three molding technologies were used in the work: vacuum infusion, impregnation under pressure, and contact molding technology from prepreg. It was experimentally found that the highest values (of the studied mechanical characteristics) are achieved when manufacturing samples using RTM technology, and the lowest when using vacuum infusion.
