Table 1 Main application fields of LFT-G long fiber reinforced pellets
Read the analysis by Chuangbo, you will get the answer.
Long glass fiber reinforced material refers to a modified polypropylene composite material containing reinforcing fibers with a length of 10 to 25 mm. After injection molding and other processes, a three-dimensional fiber structure is formed inside the product. It has higher comprehensive performance than short fiber reinforced materials, so it is widely used in various fields.
Generally speaking, the tensile strength of polypropylene materials is between 20M and 30MPa, the bending strength is between 25M and 50MPa, and the bending modulus is between 800M and 1500MPa. Fiber reinforcement is a very efficient and low-cost way to improve the strength properties of polypropylene. The mechanical properties of PP reinforced by long glass fibers can be improved several times. The tensile strength can reach more than 150MPa, the flexural strength can reach 200MPa, and the flexural modulus can reach 3000MPa~4500MPa. Such mechanical strength is completely comparable to ABS and reinforced ABS products.
At the same time, the heat resistance of long fiber reinforced materials is better. Generally, the heat resistance temperature of ABS and reinforced ABS is between 80°C and 98°C, while the heat resistance temperature of glass fiber reinforced polypropylene materials can reach 135°C to 145°C. It can be used to make axial fans and cross-flow fans in refrigeration machines such as refrigerators and air conditioners, and its cost is much lower than that of ABS reinforced products. It can also be used to manufacture inner barrels, pulsators and pulleys of high-speed washing machines to meet its high requirements for mechanical properties, and can be used in places with high temperature resistance requirements such as the base and handle of electric cookers, and electronic microwave ovens.
Carbon fiber reinforced nylon can reach and exceed the comprehensive performance of aluminum alloy, so it can play a very important role in the fields of automobile lightweight, high-speed railway and aviation.
In recent years, with the continuous optimization of long fiber production equipment and processes, the impregnation level of fibers has been significantly improved, and the appearance of the parts is excellent, which can meet the requirements of some interior and exterior parts.
At present, the development trend of the automotive industry is modular platform manufacturing. By modularly integrating common structures that use similar components, the common rate of parts and components is improved, and the process of manufacturing and process assembly is simplified, thereby greatly reducing the development and Validation-to-production cost.

Table 2 Application of long glass fiber reinforced polypropylene materials in the automotive field
The high-temperature fatigue strength of long glass fiber reinforced polypropylene at 120 ° C is twice that of ordinary reinforced polypropylene, and even 10% higher than that of glass fiber reinforced nylon, which is famous for its heat resistance. Thanks to its durability and reliability, it is widely used in electronic appliances, home appliances,
automobiles and other fields.
