Modification of epoxy compositions by ultrasound

The Modification of Epoxy Binder EDT-10

“…It must be pointed out that the results of investigating the effect of preliminary vibration on binder EDT-10 and on polymer composites based on this binder are consistent with data from studying the effect of ultrasound treatment on epoxy binders and on reinforced materials based on these binders [16,27,28].…”

“…Comparison of the results of research into the modification of binder EDT-10 using vibration and a modifying additive with published data enables us to conclude that these modification methods result in an increase in the energy of intermolecular interaction and an increase in the molecular packing density, compensating for the defectiveness of the topological structure of the crosslinked polymer [3,4,11,12,17,[27][28][29][30].…”

“…The results of tensile tests on specimens of organoplastics, given in Table 3, indicate that preliminary vibration of binder EDT-10 makes it possible to increase the strength of the organoplastic by ~4%. It must be noted that, with vibration of the binder, the degree of strengthening of the organoplastic is limited to the contribution of the strength of the binder to the strength of the organoplastic [27].…”

“…Thus, the modification of binder EDT-10 with additive OOPG enables the stability of the strength of the organoplastic to be increased considerably. This is very important, as reduction in the spread of the strength of the organoplastic makes it possible to reduce the safety factor in strength design and to increase the reliability of the articles manufactured [27].…”

Polymeric composite materials reinforced with polyacrylonitrile fibres

“…43 " 46 It was established that "antiplasticisation" is the result of the simultaneous alteration of the structure and properties of the matrix and the plasticiser associated with their compaction, which in fact improves the mechanical and other properties.…”
