Airdynamics Cannot Be Ignored
The driving resistance of the vehicle is proportional to the square of the vehicle speed, and the consumption power is proportional to the three -time square of the speed. In popular terms, whenever the speed increases, the wind resistance will increase by 4 times, and the consumption power will increase by 8 times. Perhaps the wind resistance is not the main component of driving resistance for vehicles with low speed, but for high -speed cars, wind resistance has become the main factor affecting driving resistance and fuel consumption. Studies have shown that when a truck is driving at 80km/h at a constant speed, it has 60%-70%of fuel consumption to overcome wind resistance.
Trailer Aerodynamic Devices
Improving the aerodynamic design of a trailer can reduce air drag, thereby improving fuel efficiency, lowering carbon emissions, and enhancing vehicle stability. The main devices are the trailer skirt fixed to the bottom of the trailer and the trailer tail fixed to the rear.
Side Skirts
Trailer side skirts installed on both sides of the wheels can reduce air entering the wheel area, further reducing turbulence and air resistance.
Tails
The trailer tail device can help balance the airflow at the rear of the truck, reduce the negative pressure caused by airflow separation, and thus reduce resistance.
Thermoplastic Composites for Trailer Aerodynamic Skirts and Tails
Thermoplastic composites are increasingly being used in the design and manufacture of trailer aerodynamic components. They are made of multiple layers of thermoplastic pre-impregnated unidirectional tape laid at designed angles. These materials combine light weight, high strength and durability, making them ideal for improving trailer aerodynamic efficiency.
Benefits of Thermoplastic Composites
- Lightweight
Thermoplastic composites are significantly lighter than traditional materials such as steel or aluminum. The reduced weight improves fuel efficiency and allows aerodynamic components to be added without significantly increasing the overall weight of the trailer.
- High Strength-to-Weight Ratio
Despite their light weight, thermoplastic composites offer exceptional strength and stiffness, which is critical for maintaining the structural integrity of aerodynamic components, especially at high speeds.
- Durability and Impact Resistance
These composites are extremely durable and impact-resistant, making them ideal for components that may be exposed to harsh road conditions and debris.
- Corrosion Resistance
Thermoplastic composites are corrosion-resistant, whereas metal components can degrade over time due to exposure to the elements. This ensures long-term performance and reduces maintenance costs.
- Design Flexibility
Thermoplastic composites can be molded into complex shapes, allowing for the creation of highly optimized aerodynamic designs that are difficult to achieve with traditional materials.
