Both materials have distinct properties that make them suitable for different applications. While carbon fiber is known for its exceptional strength-to-weight ratio, making it ideal for applications where weight reduction is crucial without compromising strength, plastic is generally the more affordable option.
The production of carbon fiber is complex and expensive. The cost of raw materials and the manufacturing process make carbon fiber significantly more expensive than most plastics. According to a report by MarketsandMarkets, the average cost of carbon fiber is around $15 per pound, while some plastics, such as polyethylene, can cost as little as $0.50 per pound.
Plastic is relatively inexpensive to produce, and its cost can vary widely depending on the type and quality. High-performance plastics, such as polycarbonate and ABS, offer good impact resistance and strength. ABS plastic, in particular, is known for its strength and durability, making it a popular choice for various applications, including exterior vehicle upgrades such as spoilers and side skirts.
While carbon fiber is stronger and lighter than ABS plastic, it is more prone to cracking and breaking when impacted. ABS plastic, on the other hand, may dent or bend, and it is also easier to work with as it can be painted to match very easily. For these reasons, and because it is cheaper than carbon fiber, ABS plastic is a common choice for vehicle modifications.
In summary, plastic is generally cheaper than carbon fiber due to the lower cost of raw materials and a less complex manufacturing process. This makes plastic a more economical choice for many applications, especially when high strength-to-weight ratios are not the primary concern.
