Who invented carbon fiber?

The invention of carbon fiber was the result of collaborative efforts by researchers in the UK and the US. Starting in the late 1950s, scientists and engineers, including Roger Bacon, W. Watt, R. Trent, and Dr. Frederick Brooks Jr., developed the material through experimentation and research. The breakthrough came with the creation of a new commercial carbon fiber called "T-300" by Brooks and his team at DuPont in the 1970s. Since then, carbon fiber technology has continued to advance, leading to new and improved materials with diverse applications.
