The uncommon characteristics of fiberglass composite pilings advance them an excellent building element for an extensive variety of utilization where better strength and endurance are needed. Composite sheet piling and round piles have been favorably used over the past decades in a lot of private and commercial projects with the military, and various state and local districts. The strength of fiberglass composite sheet piles in water was analyzed through the examples cut from flanges and webs of pultruded sheet pile parts. That is why it is better to use cost of sheet piling for the dock projects. The durability of this particular material is proven through a series of tests and examinations.
The examinations were conducted to estimate the water absorption at ambient temperature in total immersion, and its impact on the tensile qualities and the freeze-thaw permanence of the soaked composites. The high temperature at 70°C was applied to stimulate the tests, and 100°C (boiling water) to check the status of saturation. Fiber Reinforced Polymer (FRP) material is a new alternative in structural planning which has the advantage of very high strength to self-weight ratio. Particularly in bridge construction, which until now has a long assembly time and materials that are difficult to carry without heavy equipment, FRP is the choice in obtaining a bridge structure that is light, fast in installation, and has a capacity for large traffic loads. Currently, Fiber Reinforced Polymers (FRP) is becoming a trend in the world, both in the fields of transportation, industry, infrastructure, and settlements.
FRP was chosen as an alternative structural material because of its very high strength to self-weight ratio besides having other properties such as non-conductive, anti-corrosion, and so on. Meanwhile, until now, bridge construction materials are generally still relatively heavy elements and difficult to carry without using heavy equipment. FRP is a type of composite material consisting of a polymer resin matrix reinforced with glass or carbon fibers. FRP is widely used as a structural component in aircraft, automotive, retrofitting, and other structures including bridges. The advantages of FRP material compared to other materials are corrosion resistance, high strength, lightweight, dimensional stability, reduce the use of production equipment, has the characteristics of electrical or non-conductive insulation, does not require a large finishing process.
