Technical Advantages of Plastic Compounding Process in the Automotive Field

The application of plastic compounding process in the automotive field is extensive and in-depth. By combining different plastic substrates with reinforcing fibers (such as glass fiber, carbon fiber) or other functional materials, composite materials with lightweight, high strength, corrosion resistance and other characteristics are formed, which significantly improves the performance of automobiles and promotes technological innovation in the industry. The following is an analysis of technical advantages:

1. Performance optimization

Improved mechanical properties: Fiber reinforcement significantly improves the strength and modulus of materials. For example, the impact strength of GMT sheets is 3-5 times higher than that of LFT sheets, and the fiber length of CMT sheets is 25-100mm, and the comprehensive performance is better than LFT and GMT.

Functional integration: Through the composite process, electrical conductivity, thermal conductivity, electromagnetic shielding and other functions can be integrated. For example, carbon fiber composite materials are used in new energy vehicle battery brackets, which have both structural support and electromagnetic shielding.

2. Cost-effectiveness

Reduced material cost: Plastic composite materials are cheaper than metals and have low processing energy consumption. For example, glass fiber reinforced polypropylene (GMT) is used in bumpers, pedals and other parts, reducing weight by more than 20% and reducing material costs by 20%.

Improved production efficiency: Injection-molded thermoplastic composite materials (such as LFT-PP) have a short molding cycle and are suitable for large-scale production; compression molding processes (such as GMT and CMT) support integrated molding of complex structures and reduce assembly processes.

3. Environmental protection and sustainability

Recyclable: Thermoplastic composite materials can be melted and reshaped multiple times, meeting the requirements of the circular economy. For example, the Nissan Rogue liftgate uses 100% recyclable TPO and LFT-PP materials.

Lightweight emission reduction: Reducing vehicle weight can reduce fuel consumption and exhaust emissions, while improving the range of new energy vehicles. For example, for every 100kg reduction in vehicle weight, the fuel consumption of a fuel vehicle per 100 kilometers is reduced by about 0.5L, and the range of an electric vehicle is increased by 5-8km.
