Fiber glass reinforced polymer (FRP) is up to 70% lighter than steel, FRP materials, unlike steel and aluminum, offer a high strength-to-weight ratio. This is particularly beneficial in applications where weight is a critical factor but high strength is still required, such as in the manufacture of aircraft and automobiles.
FRP is electrically & thermally non-conductive and radio frequency transparent, making it ideal
for applications where these characteristics are desired, such as in the
construction of telecommunications structures and electrical equipment
enclosures.
FRP products are resistant to aggressive chemicals, and liquids. This makes them ideal for wastewater treatment plants, swimming pools, cooling towers and construction, where there is a risk of corrosion. The resistance to environmental influences increases the life cycle of the material and object that fiberglass is applied to. Also, ensures visual aesthetics for a longer period of time.
FRP material is an efficient solution for sound insulation and the creation of acoustics, fiberglass composites can be used in just about any type of applications.
Unlike steel and aluminum, FRP can be molded into various complex shapes
and sizes without any significant alteration to its properties. This gives it
an advantage in many different manufacturing and construction fields.
While the initial investment may be higher, the long-term operating costs of FRP are lower because of its durability and low maintenance requirements when compared to steel and aluminum.
