Due to the increasing number of catastrophic floods around the world, creation of an effective system to protect against natural disasters became particularly relevant. The paper investigates introduction of the basalt fiber to reinforce the composite sheet piles. Influence of the reinforcing fiber interlacing type on the nature of plastics destruction was established. Results of the work prove that basalt plastic (BP) exhibits higher climatic resistance than the fiberglass plastic (FGP). After post-curing, strength characteristics relative to the second year were decreasing by 15% with BP and by 22% with FGP in extension, and the strength limit in bending was decreasing by 12% with BP and by 47% with FGP. It was experimentally shown that under a long-term stationary thermal and humidity effect of 23°C/68RH, diffusion was observed on the basalt and fiberglass plastics consisting of two stages. The first stage had a satisfactory statistical error and was adequately approximated by the Fick’s diffusion model and the relaxation model. The second stage had an unsatisfactory statistical error for approximation and was of the spasmodic nature, while the jump in FGP was the largest indicating that the FGP was more susceptible to destruction exposed to the influence of long-term temperature and humidity regime of 23○С/68 RH, than the BP. |
