Why Do Racing Cars Prefer Using Carbon Fiber Material?

1 Answers

Racing cars prefer using carbon fiber material due to its unique properties: lightweight, high strength, and excellent braking performance. Carbon fiber is a high-end new material, a high-strength, high-modulus fiber with a carbon content exceeding 95%. Here are some relevant details: 1. The density of carbon fiber is only one-fourth that of steel, but its tensile strength exceeds 3500Mpa, which is 8 to 10 times that of ordinary automotive steel. For materials with the same cross-sectional area, carbon fiber can withstand several times the force of steel. Currently, most car bodies are made of steel. If they were entirely replaced with carbon fiber, the vehicle weight would be reduced by approximately 300kg. Reducing the car's weight correspondingly decreases fuel consumption, making it both environmentally friendly and energy-efficient. 2. Carbon fiber brake discs can be seen on many professional racing cars. Carbon fiber has excellent high-temperature resistance and outstanding braking performance. Within a distance of 50 meters, it can reduce a car's speed from 300km/h to 50km/h.

Why Should You Lift Your Car's Windshield Wipers in Snowy Weather?

The reasons for lifting your car's windshield wipers in snowy weather: 1. To protect the wipers—winter temperatures are low, and wipers can easily freeze. Many people instinctively turn on the wipers, which can lead to motor burnout. 2. To make it easier to clean the windshield—after snow, wipers often freeze to the windshield, requiring timely snow removal. Therefore, lifting the wipers in advance reduces the difficulty of snow removal. The correct snow removal method involves first clearing the snow from the windshield, then using the car's heater to defrost the windshield by setting the air conditioning to warm air and directing it toward the windshield. If the wipers are frozen, they will also thaw as the windshield warms up. Only after completely removing ice and snow from the windshield should you proceed with other operations.
