| Title of the article | The study of the physical and mechanical properties of nanomodified basalt roving and based on it a composite material |
| Abstract. | In this study, experimental testing of nanomodified film forming of the LLC «Scientific Production Firm (SPF) «RECON» (Kazan) company production in the production of basalt fiber of LLC «Kamennyy vek» (Dubna) was conducted, physical and mechanical characteristics of obtained basalt rovings and composite material on its basis were studied. In the manufacture of nano-modified emulsions as additives were used: - Multilayer CNT – in the form of solid concentrates (masterbatches) under the brand name Graphistrength С S1-25 (containing CNT – 25 wt. %, dispersed in a medium of DGEBA monomer and bisphenol A (producer – «Arkema» company, France). The work carried out in LLC «Kamennyy vek» confirms the possibility of using nanomodified film formers in formulations of the sizing composition for basalt continuous fibers. Nanomodifing of basalt fiber CNTs surface through a sizer has a positive effect on the characteristics of basalt roving, namely: - physico-mechanical properties of basalt roving: the mechanical strength of harness dry roving is increased from 781 to 704 mN / tex (11 %) (using emulsion based epoxy resin, manufactured in Europe – D.E.R. 331 as a part of sizer); - fiber adhesion to the cold curing epoxy binder: thus, the adhesion increase of 17,3 % – in the case of the use as a film-forming agent as a part of the epoxy resin emulsion sizer NPEL128S (with 0,003 pbw CNT), and to 25,2 % – in the case of the use as a film-forming agent as a part of the epoxy resin emulsion sizer DER 331 (with 0,003 pbw CNT). With the introduction of CNTs in the sizing the growth of physical and mechanical properties of basalt rebar produced by nanomodified fiber is observed. The maximum effect of the introduction of CNT observed at joint nanomodification of sizing on the surface of basalt fiber and epoxy binder as well. |
