Introduction to Carbon Fiber
Carbon fiber, also known as graphite fiber, is a type of fiber-reinforced polymer that consists of long, thin strands of carbon atoms. These strands are woven together to form a fabric-like material that is incredibly strong, yet remarkably lightweight. Carbon fiber has a unique combination of properties that make it an ideal material for a wide range of applications, including:
Its high strength-to-weight ratio, which makes it perfect for use in aircraft and spacecraft
Its resistance to fatigue, corrosion, and extreme temperatures
Its ability to be molded into complex shapes and forms
The Early Days of Carbon Fiber Research
The discovery of carbon fiber dates back to the late 19th century, when scientists first began experimenting with the properties of carbon. In the 1860s, a British chemist named Joseph Swan developed a method for producing carbon fibers through the pyrolysis of cellulose. However, these early fibers were not very strong and were primarily used for making incandescent light bulbs.
It wasn’t until the 1950s and 1960s that researchers began to explore the potential of carbon fibers as a reinforcement material for polymers. A team of scientists at the Royal Aircraft Establishment in the United Kingdom, led by William Watt, developed a method for producing high-strength carbon fibers through the pyrolysis of polyacrylonitrile (PAN). This breakthrough led to the creation of the first commercial carbon fiber products, which were used in the aerospace industry.
The Role of Roger Bacon
One of the key figures in the development of modern carbon fiber is Roger Bacon, an American physicist who worked at the Union Carbide Parma Technical Center in Ohio. In the 1960s, Bacon developed a method for producing high-strength carbon fibers through the pyrolysis of PAN, similar to the process developed by Watt and his team. However, Bacon’s method involved the use of a different type of PAN precursor, which resulted in fibers with even higher strength and stiffness.
Bacon’s work on carbon fiber led to the development of a new type of fiber known as Thornel, which was introduced in the late 1960s. Thornel fibers were used in a variety of applications, including aerospace, automotive, and sports equipment. Bacon’s contributions to the development of carbon fiber were recognized with numerous awards, including the Perkin Medal and the National Medal of Science.
