Light Weight 300gsm Carbon Fiber CFRP Wrap For Weak Substrate Strengthening
Carbon Fiber-reinforced polymer (CFRPwrap ) systems are simply defined as highstrength and lightweight reinforcements created by combining carbon (CFRP) with a polymer material (epoxy resin). The performance characteristics of CFRP wrap strengthening system have become increasingly popular in construction and retrofit applications, specifically in aging, damaged, deteriorating or overloaded concrete structures.
The most common CFRP wrap systems for concrete strengthening applications are carbon fiber based (CFRP). Carbon has superior mechanical properties and higher tensile strength, stiffness, and durability compared with glass fiber based systems. The use of prefabricated CFRP bars and plates is typically limited to straight or slightly curved surfaces; for example, the top side or underside of slabs and beams. Prefabricated FRP elements are typically stiff and cannot be bent on site to wrap around columns or beams.
