Strength And Stiffness

This paper presents a method for evaluating the effect of loading parameters on the strength of ani-sotropic unidirectional carbon-fiber composite material under tension in the plane of orientation of the fibers. Experimentally studied mechanisms of deformation and fracture of the samples shows the dependence of the mechanical properties of reinforced carbon fiber reinforced plastics. The objective of the study is to determine the applicability of CFRP for strengthening by external reinforcement has lost the strength of the stretched zones of concrete elements, as well as analysis of the degree of influence of parameters of loading of the structures on their strength after amplification.

Fiber Reinforced Plastics

The mechanism of using prestressed carbon fiber reinforced plastics (Pre-CFRP) sheet to strengthen reinforced concrete beams with anti-arch deflection method was proposed. And then the corresponding theoretical analysis was derived, and the effectiveness of this reinforcement method is verified by experiment in laboratory to improve the girders stiffness and cracking load.

Determining Factor

Studies and experimental data on the microstructure of the surface of samples of epoxy сarbon-fiber-reinforced plastics that have undergone long-term (up to 5 years) climatic aging in different climatic zones of Russia have been conducted: under conditions of the industrial zone of temperate climate (Moscow, MTsKI); temperate warm climate (Gelendzhik, GTsKI); a warm humid climate (Sochi, GNIP RAS). It is established that the determining factor for aging of carbon plastics is the duration of the complex effect of climatic factors: the longer the period of climatic aging, the more significant changes occur in the microstructure of the surface of the materials. The intensity of the aging process and the degree of microstructural changes in the surface of carbon plastics are affected by the features of the climatic zone. general regularities and features of the destruction of the surface of carbon plastics after a long-term exposure to climatic factors have been established on the basis of the analysis and systematization of the results of microstructural studies.
