A composite material made of glass fibers woven together and bound with resin, used for boats, cars, insulation, and other applications requiring strength and lightweight properties.
From 'fibre' (British spelling of fiber, from Latin 'fibra') plus 'glass' (from Old English 'glaes'), a term coined in the early 20th century when this composite material was invented.
Fiberglass revolutionized boat-building in the 1950s—it's strong as steel but weighs less, doesn't rot like wood, and enabled affordable leisure boats that changed how millions enjoyed water sports.
