How was fiberglass discovered?

Answer 1

Fiberglass was not discovered, it was invented.

Plastic resins are often too brittle or two elastic to be usable for many purposes. Glass fiber is very strong and does not stretch but breaks when flexed. By laying out alternating layers of glass fiber oriented in different directions then saturating this glass fiber mesh in plastic resin you create fiberglass, a composite material that is stronger and more durable than either of the materials used to make it.

Fiberglass was the first composite material invented.

Note: wood is a natural composite material that trees have been making for hundreds of millions of years before there were humans; wood was discovered because it existed before we knew about it.

Answer 2

Fiberglass was discovered in the 1930s by Russell Games Slayter and John H. Thomas at Owens-Illinois Glass Company. They found that when molten glass was drawn into fibers, it created a strong and lightweight material known as fiberglass. This discovery revolutionized various industries, including construction, automotive, and aerospace.
