Carbon Fiber Composite Materials and Carbon Reduction
Carbon fiber composite materials play a significant role in achieving carbon reduction. When used to replace conventional materials in aircraft, cars, and other modes of transportation, they can substantially cut the weight of these vehicles. The resulting higher fuel efficiency leads to a notable decrease in CO₂ emissions. The reduction in CO₂ emissions far outweighs the amount produced during carbon fiber manufacturing. In addition, carbon fiber composites are widely used in large-scale wind turbine blades, helping to boost wind power output and further contributing to carbon reduction efforts.
Precautions for Using Carbon Fiber
Individual carbon fibers are extremely thin and prone to breaking during use, forming broken fibers. These broken carbon fibers can become airborne and pose risks to human health and equipment. Therefore, it is essential to handle carbon fiber materials carefully. Local exhaust ventilation should be used during handling. Also, carbon fiber waste should be separated from general waste and disposed of as industrial waste.
Effects of Carbon Fiber on Humans and Equipment
Carbon fibers possess a certain level of conductivity. Airborne broken carbon fibers can cause short circuits if they enter equipment. Thus, it is crucial to protect electrical systems from carbon fiber intrusion. Since carbon fibers are rigid and have a small diameter, they can cause itching or pain if they adhere to the skin or mucous membranes. To minimize exposure in carbon fiber work environments, it is advisable to limit skin and mucous membrane contact. If carbon fibers do adhere to the skin, rinse with water instead of rubbing.
Storing Carbon Fiber Prepreg
Prepreg, typically made from thermosetting resins, will cure at specific temperatures. Unless used immediately upon delivery, it should be stored at -18ºC or lower. When stored frozen in a refrigerator, it is recommended to seal the material with packaging film and place it horizontally.
