The article presents the results of studies confirming the advantages of plasma treatment in the production of glass-filled composite materials based on polyamides, which consist in environmental friendliness, resource saving and no dependence on chemical solutions that plasma treatment offers compared to traditional methods. By optimizing processing parameters, the study also explores how plasma processing can manipulate surface layer characteristics and material structure to improve cer-tain glass fiber characteristics without sacrificing other properties.
As part of the study, experiments were carried out to study the effect of low-energy ions generated by high-frequency plasma on the technological characteristics of glass fibers. Previous studies have shown that plasma treatment in various gaseous media (argon, air, propane-butane mixture) makes it possible to remove the lubricant from the fiberglass surface, activate its surface, and increase adhesion in the polymer-filler system.
Capillarity tests were carried out to evaluate the adhesion characteristics of the plasma-treated glass fibers. The results showed a direct relationship between the increase in the capillarity index, the dura-tion and intensity of the plasma treatment. As a result of the study, the optimal processing parameters were determined to achieve the desired adhesive characteristics, as a result of which the adhesive strength increased by 1.5-1.7 times.
The results of the study confirmed the persistence of the effect of plasma treatment over time, and therefore, it is recommended to use modified glass fibers to reinforce polymer matrices during the first 10-25 days after treatment.
The data obtained make it possible to recommend plasma treatment for the modification of glass fibers in the production of reinforced polymer composites.
