| Title of the article | Study of deformability, creep behavior of fiberglass plastics externally reinforced with carbon plastics |
| Abstract. | Problem statement. One of the methods of improving the stiffness characteristics of FRP in construction practice is their external reinforcement with the use of carbon composites. The deformability of such systems is due to both the selection of components and the study of their creep. The purpose of this work is to study the deformability, temperature and time dependence of creep of fiberglass plastics externally reinforced with carbon fabrics on epoxy adhesives with different amounts of plasticizers. The objectives of the study are: investigation of deformation of fiberglass plastics externally reinforced with carbon fabrics on epoxy binder with different content of plasticizers in the area of elastic deformations at normal temperature, investigation of the creep of samples on four-point bending by the method of step isotherms. Results. We investigated the deformability, temperature-time dependence of creep of the system "pultrusion fiberglass - epoxy adhesive compositions with different amounts of plasticizers - carbon fabric". According to creep curves with the increase of plasticizers in the composition of epoxy resin, an increase in the deformability of the systems in the studied temperature intervals is observed. An approach to the experimental investigation of the temperature-time dependence of creep of systems using the method of step isotherms is proposed. Conclusions. The significance of the obtained results in the construction industry lies in the use of the method of step isotherms for the experimental study of the temperature-time dependence of the creep of fiberglass plastics externally reinforced with carbon plastics and is recommended in solving scientific and engineering problems. |
