Abstract

The epoxy resin in the form of Etal Inject-T compound, Sigratex KDK carbon fabric, Taunit-M carbon nanotubes conditionally named as CNT-1, as well as functionalized (modified) variety of them by grafting to the surface of new chemical groups: carboxylated ‒ CNT-2, carboxyl-hydroxylated ‒ CNT-3, amidated ‒ CNT-4 were used in the work. The experiments were performed on the compression strength and bending strength of the samples. The injection of CNT-1 into epoxy resin or carbon fiber reinforced plastic did not produce the hardening. The injection of 0.05% of CNT-2 into the epoxy resin had the following effect: there is no influence in the area of quasielastic strains, the hardening was up to 25% in the areas of plastic and elastic-plastic strain. The injection of 0.15% of functionalized carbon nanotubes into the carbon fiber reinforced plastic produced the hardening for compression with CNT-2 ‒ 6%, CNT-3 ‒ 12%, CNT-4 – 17%, for bending – CNT-2 – 44%, CNT-3 – 59%, CNT-4 – 132%. It is established that with an increase in the strain rate of epoxy resin from 1 to 5 mm/min the areas of plastic and elastic-plastic strain gradually are reduced, there is only quasielastic strain with brittle fracture at 20 mm/min, this value can be accepted as its strength characteristic. With an increase in the strain rate of carbon fiber reinforced plastic from 1 to 20 mm/min the compression strength gradually increases from 398 MPa to 425 MPa, and then stabilizes.
