Vliv působení zvýšených teplot na odolnost kompozitní výztuže

Abstract

This thesis focuses on the effect of elevated temperatures on the behavior of composite reinforcements used in construction. The theoretical part analyzes the properties of the three most commonly used types of FRP reinforcements—BFRP (basalt), GFRP (glass), and CFRP (carbon)—and compares them in terms of thermal resistance, strength, and suitability for application in fire-risk environments. Furthermore, the thermal characteristics of various types of resins used as matrices are presented. The thesis also includes a proposed experimental procedure for tensile strength testing at elevated temperatures, with an emphasis on reliable sample anchoring in accordance with ISO 10406-1. The results of this thesis provide a foundation for future practical testing and the application of composite reinforcements in fire-exposed structural elements.
