FRP Application and Structural Engineering Innovation of High Performance Materials Based on Mechanical Analysis

Abstract

FRP (Fiber Reinforced Composite) has been widely used in the reinforcement of concrete structures in recent years. FRP composites, as high strength, lightweight and high performance reinforcement materials, have been widely used not only in China, but also in foreign countries and in water and soil engineering. China has made a series of achievements in the development of high-performance FRP materials and their products suitable for civil engineering applications, and in the application of FRP key technologies in civil engineering. In the development of concrete structures in the new century, new requirements and challenges have been put forward for materials. Because FRP is a frontal composite material composed of many kinds of materials, its common advantages are light weight, high strength and elastic modulus, fatigue resistance, long service time, good corrosion resistance and low thermal expansion coefficient, etc. FPR is a new type of high performance material, which is of great significance to the sustainable development of civil engineering industry in our country. This paper introduces the properties and forms of FRP materials commonly used in structural engineering, puts forward the rational application of FRP and its structure, and analyses its advantages and disadvantages in order to promote the application and research of this new type of high performance material in civil engineering in China.
