Structural Characteristics of Pultruded FRP Composite Experienced Freezing and Thawing Cyclic Temperature

Abstract:

Due to the advantages of FRP composite such as corrosion resistance, light weight, high specific strength and stiffness, flexibility, etc., the use of FRP composite in construction sites is increasing steadily. Especially, high corrosion resistance is a very strong point of FRP composite. Although the FRP composite has many advantages, the material properties of FRP composite under various environmental conditions at the construction sites are not well investigated. In this paper, we present the results of experimental investigations of FRP composite experiencing freezing and thawing cyclic temperature. In this investigation, we performed experimental studies to find the stress versus strain characteristics of FRP composite experiencing freezing and thawing cyclic temperature variation. In the experimental program, strength and stiffness of the pultruded FRP composite specimens under uniaxial tension affected by the freezing and thawing temperature change mechanism are evaluated and the results are discussed.
