Effect of functionalized multiwalled carbon nanotubes on the feasibility of fabrication of composite glass fiber reinforced plastic rebars

详细

The effect of COOH-functionalized multiwalled carbon nanotubes on the temperature–velocity conditions of the fabrication of composite glass fiber reinforced plastic rebars (so-called needletrusion) used in building was studied. EPIKOTE 862 epoxy oligomer (Bisphenol F diglycidyl ether) in combination with EPICUREW curing agent (aromatic diamine) in 100 : 26.4 ratio was used as binder. The use of functionalized multiwalled carbon nanotubes as additives to the unmodified epoxy binder for fabrication of composite materials by needletrusion allows production of high-quality items with the required characteristics without loss in the production capacity. It is preferable to introduce nanotubes in an amount of no more than 0.2 wt %.
