Question

In construction, what does FRP stand for?

• A. Fibre Reinforced Polymer
• B. Flexible Reinforcement Panel
• C. Fast-Repairing Plastic
• D. Fire-Resistant Particleboard

Hint:

(ő) \textbf{FRP} is an acronym for \textbf{Fibre Reinforced Polymer} or \textbf{Fiber Reinforced Plastic}.
(Œ) It is a composite material made of reinforcing fibers (e.g., glass, carbon, aramid) embedded in a polymer matrix (e.g., epoxy, polyester).
(œ) FRPs are used in construction for their high strength, light weight, corrosion resistance, and durability.

Answer 1

The Correct Option is A

In the context of construction materials and structural engineering, FRP is a common acronym. FRP stands for Fibre Reinforced Polymer (or Fiber Reinforced Plastic). FRP composites consist of:
(ň) Reinforcing fibers: These provide strength and stiffness. Common types include glass fibers (GFRP), carbon fibers (CFRP), aramid fibers (AFRP, e.g., Kevlar), or basalt fibers (BFRP).
(ʼn) A polymer matrix (resin): This binds the fibers together, transfers load between fibers, and protects the fibers from environmental damage. Common matrix materials include epoxy, polyester, vinyl ester, or phenolic resins. FRP composites are known for their high strength-to-weight ratio, corrosion resistance, durability, and design flexibility. They are used in a wide range of construction applications, such as:
(Ŋ) Strengthening and retrofitting existing structures (e.g., concrete columns, beams, slabs).
(ŋ) New construction elements (e.g., reinforcing bars for concrete, structural profiles, bridge decks, panels).
(Ō) Pipes, tanks, and other infrastructure components. Let's check the options:
(ō) (a) Fibre Reinforced Polymer: This is the correct and standard full form of FRP in construction and materials science.
(Ŏ) (b) Flexible Reinforcement Panel: While FRPs can be made into panels and some might be flexible, this is not what the acronym stands for.
(ŏ) (c) Fast-Repairing Plastic: This is not the meaning of FRP.
(Ő) (d) Fire-Resistant Particleboard: Particleboard is a wood-based panel. FRP is a polymer composite with fibers. While some FRPs can be made fire-resistant, this is not the general definition. Therefore, FRP stands for Fibre Reinforced Polymer. \[ \boxed{\text{Fibre Reinforced Polymer}} \]
