Fiber reinforced polymers are referred by different names across the world depending upon the used components, generally as GRP (glass reinforced plastic), FRC (fiber reinforced plastic) and PMC (Polymer Matrix Composites). FRP composites are polymer or plastic matrix, either integrated with thermoplastic or thermoset features that are combined with fiber or other supporting material at a proper ratio in order to deliver reinforcing function in a particular dimension or in multiple dimensions. Resins, fillers, modifiers, additives and reinforcements such as forms and fibers are the prime ingredients of FRP.
Each of the ingredients is equally vital and plays significant roles in shaping up the final outcome and determining the intrinsic formations of the finished FRP structural profile. The mechanical strength comes from the used reinforcement.
Special features of FRP
•Through the selection of resin, reinforcement, resin as well as manufacturing process the design of FRP composite can be engineered to make it suitable for particular specifications regarding performance and cost-effectiveness. With the right selection of manufacturers, one can obtain constructible solution compliant to his design idea.
•FRP falls into the category of composite material. This sort of material generally consists of two or more components and each of them retains their physical characteristics and respective chemical even when combined together. Composite materials hold intrinsic dimensional stability potential owing to the unique formulation.
•The slip resistible property of FRP readily makes it the idyllic choice for manufacturing stair nosing. Marine industry and industrial facilities situated in a highly corrosive environment and susceptible to chemical exposure are greatly benefitted with the use of this nosing system.
•FRP made structural properties can be crafted to augment the number beneficial aspects and designed to gain the best of both worlds. Engineers often select FRP when it comes to applying it under extreme conditions incorporated with features like stringent dimensional stability.
•Significant differences exist in terms of mechanical properties while evaluating FRP against metals like aluminum and steel. FRP is anisotropic in nature that defines it has mechanical properties in the similar direction of the applied load, better say the best mechanical properties lies in the same direction of fiber placement. On the other hand, aluminum and steel are isotropic in nature devised with uniform properties in each direction, indifferent to the applied load.
•Besides having great dimensional stability FRP structures also features properties like incredible weight to strength ratio, damage tolerance, notch sensitivity. It’s light in weight, sturdy, non-corrosive in nature and also abrasion resistant. Structural profiles like FRP grating is resistant to fatigue and also safeguard the structural integrity of the footbridge, work platform and floor.
Simpler repairing process, high strength, ease of installation, lower life cycle cost along with zero to meager maintenance cost and excellent durability makes FRP a more reasonable choice.
