Comparative Study of the Impregnability of High-Strength Glass and Basalt Fibers

Comparative studies of the impregnability of high-strength and basalt fibers, treated and untreated by emulsions of film-formers, by epoxy binders with different curing agents were conducted. Differences in the surface treatment of high-strength and basalt fibers were found by determining the impregnation along the height of capillary rise of the binder. The effect of surface treatment on the change in strength of the tested filaments and microplastics based on them was determined.
