Within the Fiber Reinforced Plastics (FRP) segmentation framework, application categories drive the bulk of revenue. The construction sector, accounting for roughly 35 % of total sales, leverages FRP for corrosion‑resistant piping, façade panels, and reinforcement bars, reflecting its high volume and long‑term replacement cycles. Automotive usage, representing about 25 %, focuses on lightweight body panels, structural components, and interior trim, where weight reduction translates directly into fuel‑efficiency gains and regulatory compliance. Aerospace, contributing near 20 %, adopts high‑performance carbon‑based FRP for airframe skins, interior fittings, and engine components, justified by stringent strength‑to‑weight requirements. Electrical and electronics applications, at approximately 12 %, employ FRP for printed circuit board substrates, housings, and insulating components, driven by dielectric properties and thermal stability. The marine segment, though smaller at 8 %, utilizes FRP for hulls, decks, and offshore structures, capitalizing on its resistance to saltwater corrosion. Collectively, these application sub‑segments delineate the market taxonomy and explain the distribution of the global FRP market size.
