Fibre- Wrapping:
A Fiber Reinforced Polymer (FRP) composite is defined as a polymer (plastic) matrix, either thermoset or thermoplastic, that is reinforced (combined) with a fibre or other reinforcing material with a sufficient aspect ratio(length to thickness) to provide a discernable reinforcing function in one or more directions. There are several situations in which a civil structure would require strengthening or rehabilitation due to lack of strength, stiffness, ductility and durability. Some common situations where a structure needs strengthening during its lifespan are
Seismic retrofit according to current code requirements.
Upgraded loading requirements; damage by accidents and environmental conditions.
Initial design flaws
Change of usage.
Testing
Cube Testing is done extensively over cylindrical and rectangular cubes with fiber wrapped system and they show improved enhancement in their flextural and compressive strengths.
Testing
Tesile Strength ASTM D-3039-93
