what is a rear wing
“Tail spoiler”, also known as “spoiler”, is more common in sports cars and sports cars, which can effectively reduce the air resistance generated by the car at high speed, save fuel, and have a good appearance and decoration effect.
The main function of the rear wing is to make the air exert the fourth force on the car, that is, the adhesion to the ground. It can offset part of the lift, control the car to float up, reduce the influence of wind resistance, so that the car can drive close to the road, thereby improving the speed of the car. Driving stability.
HRC one-piece carbon fiber rear wing
The existing tail wing process mostly adopts plastic injection molding or vacuum infusion molding of fiber composite materials, but has the following disadvantages:
The rigidity and strength of the injection-molded rear wing are insufficient, and the service life is short;
The surface appearance of the plastic tail fin and the vacuum injection molding tail fin is not aesthetically pleasing, and cannot meet the requirements of high-end models that pursue a unique and exquisite appearance;
The traditional tail fin is combined into an overall shape through the secondary bonding process, but this manufacturing method has the shortcomings of low processing efficiency, easy warping and deformation of the product, and the bonding gap seriously affects the appearance of the shape;
In addition, the automotive exterior parts and structural parts previously manufactured by vacuum infusion process or PCM prepreg molding in China are basically at the level of proofing, and their size and performance are unstable, which cannot meet the requirements of batch and stability of the automotive industry.
The HRC team explored a series of manufacturing and testing technologies such as material verification, structural design, simulation analysis, mold development, CNC tooling development, bonding tooling development, and testing technology, overcame difficulties one by one, and successfully developed a one-piece carbon fiber tail. It has complex shape, beautiful appearance, demanding functional requirements, strong mechanical properties, and meets the requirements of lightweight, with a total weight of less than 1.6 kg.

Advantages of carbon fiber rear wing
Product integrated molding technology. Products can be produced stably in batches, which not only improves production efficiency, but also saves development costs and reduces product costs.
The one-piece molding process reduces the bonding process and avoids warping and deformation during the bonding process. In addition, the unique design of this product can highlight the sporty feeling of the whole vehicle.
It is easy to install and facilitate subsequent disassembly and maintenance, meeting customers’ needs for the convenience of vehicle assembly. By using the combination of rivet bolt mechanical connection and plastic snap connection, the assembly method is safer and more reliable.
Reasonable product parting line design, realize the product parting line control within 0.2mm, to ensure the beautiful effect of 3K texture on the surface.
The appearance is protected by high-brightness paint, which meets the light aging test for more than 2000 hours and the heat aging performance test, and at the same time ensures the beautiful appearance of the product.
The total weight of the product is less than 1.6 kg. While achieving light weight, it meets more than 30 performance verifications such as 5-200HZ high-frequency vibration test and -30°C low-temperature impact test.
The internal hollow structure design greatly reduces the weight of the product, effectively reducing wind resistance and fuel consumption. Tests show that the assembly of this product can increase the downforce at the maximum speed from 11kg to 40kg under the condition that the wind resistance coefficient is basically unchanged, which greatly enhances the handling stability.
Carbon fiber rear wing application
The product has a number of independent intellectual property rights and has been mass-produced. The market feedback and customer satisfaction of this product are excellent, which greatly promotes the development and application of carbon fiber parts in the automotive industry.
