Carbon fiber has the ability to take the place of conventionally used materials such as steel and aluminum in industries because of its better properties. Having a tensile strength of up to 500,000 psi makes it five times stronger than steel while weighing only 30% as much. These features are highly intended for applications within aerospace, automotive, and construction where strength with lessened weight is needed.
In the aerospace industry, the Boeing 787 Dreamliner has more than 50% carbon fiber in its structure, reducing the weight by about 20% compared to traditional aircraft. This leads to a fuel saving of around 10% to 15% per flight. Similarly, Formula 1 cars use carbon fiber extensively for their chassis, enabling them to reach very high speeds while maintaining structural integrity during collisions.
Carbon fiber is being adopted piece by piece in the automotive industry for hoods, roof panels, and body frames. The body of BMW’s i3 electric vehicle is made from CFRP, which reduces its weight by 250 kilograms compared to conventional steel structures. This greatly improves energy efficiency and extends battery range-critical factors in electric mobility.
Still, price is a major impediment: at $5 to $25 per pound, carbon fiber is much pricier than steel, at around $0.50 to $1 per pound. But manufacturing process advances in the future-like automated fibre placement and techniques for recycling-will shave costs by as much as 30% over the coming decade.
Elon Musk once said, “The future of engineering lies in the smart use of materials that maximize efficiency.” This is also in line with the increasing use of carbon fiber in renewable energy, especially for wind turbine blades. The latest turbines use carbon fiber to achieve lengths of over 80 meters, which enables capturing more energy while sustaining structural rigidity for extreme wind loads.
Despite its advantages, carbon fiber is not universally applicable. Its brittleness under specific conditions limits its use in high-impact applications like construction. Additionally, recycling carbon fiber remains challenging, with current methods recovering only 70% to 80% of its original strength.
In the end, carbon fiber has great potential for use in place of traditional materials in fields where weight, strength, and efficiency are a matter of concern.
