Drivers should all know that air resistance (also known as wind resistance) has always been a major enemy of trucks. Trucks have a huge windward area, a high chassis from the ground, and a square rear mounted carriage, which is highly susceptible to the influence of air resistance in appearance. So what devices are there on trucks designed to reduce wind resistance?
For example, roof/side deflectors, side skirts, low bumper, cargo side deflectors, and rear deflectors.
So, what material is the deflector and shroud on the truck made of? In the fiercely competitive market, fiberglass materials are favored due to their lightweight, high-strength, corrosion resistance, safety and reliability, and many other characteristics.
Fiberglass reinforced plastic is a composite material that uses glass fiber and its products (such as glass fiber cloth, felt, yarn, etc.) as reinforcing materials, and synthetic resin as the matrix material.
Lightweight, high-strength, corrosion-resistant Vehicles are widely used
Due to the characteristics of low investment, short production cycle, and strong designability, fiberglass materials are currently widely used in many places on trucks. A few years ago, domestic trucks had a single and rigid design and the personalized appearance was not common. With the rapid development of domestic highways, the development of long-distance transportation has been greatly stimulated. However, due to the difficulty in designing the overall personalized appearance of the driver's cab steel, the cost of mold design was high. In the later stage of welding multiple panels, corrosion and leakage are prone to occur. So fiberglass cab cover has become the choice of many manufacturers.
Fiberglass materials have the characteristics of lightweight and high strength. The density ranges from 1.5 to 2.0, only 1/4 to 1/5 that of carbon steel, and even lower than that of aluminum. Compared with 08F steel, the strength of 2.5mm thick fiberglass is equivalent to 1mm thick steel. In addition, fiberglass can be flexibly designed for product structure with better overall shape and excellent processability according to demands. The molding process can be flexibly selected based on the shape, purpose, and quantity of the product. The molding process is simple and can be formed in one go. It has good corrosion resistance and good resistance to atmospheric, water, and general concentrations of acid, alkali, and salt. So, many trucks use fiberglass materials for their front bumpers, front covers, skirts, and flow deflectors currently.
