By adding materials containing 20%, 30% and 40% carbon fiber reinforced grades, BASF is expanding its Ultramid® Advanced polyphthalamide (PPA) product portfolio. The advantage of these new materials is that they can safely replace aluminum and magnesium to make ultra-light parts without affecting strength and rigidity, and they are also conductive. These new grades of products integrate the characteristics and advantages of PA9T materials, making them stand out from the existing carbon fiber reinforced PPAs products on the market: low water absorption brings high dimensional stability, excellent chemical resistance and hydrolysis resistance , And high strength and high modulus. These new carbon fiber reinforced grades can be used to manufacture automotive structural parts on body, chassis and powertrain, industrial pumps, fans, gears and compressors, and stable and ultra-light components used in the consumer electronics industry.
BASF's new CF grade materials help different industries achieve functional integration and weight reduction
The mechanical properties of the new carbon fiber reinforced PPA grade can be adjusted through the selection and content of carbon fiber and through additive technology. N3HC8 containing 40% carbon fiber has better strength and modulus than magnesium and aluminum at a temperature of 80°C.
"Our new PPA carbon fiber reinforced compound is an ideal metal substitute material, which is not only evaluated from the perspective of material performance." Relevant personnel said, "Recently, we have seen that magnesium producers in different countries are facing safety issues. , Which makes the supply unpredictable. The manufacture of parts with magnesium or aluminum also requires additional post-processing and tools, which will increase the cost of the system. Since the use of our new level of PPA can reduce weight by 25% to 30%, it means that we are traditional Metal parts provide a safe, economical and high-performance alternative material."
Combined with BASF's simulation software, the correct model can be established to simulate the behavior of parts and optimize the shape of the mold. Therefore, the CF level helps different industries to achieve functional integration and weight reduction: electric vehicles or fuel cell vehicles can extend the cruising range by reducing the weight of structural components or power transmission components; consumer electronics products can be provided by the new PPA materials High strength and high rigidity, excellent dimensional stability, extremely low weight and good processability, can obtain light and thin precision structure; heavy, high load and long-term durable industrial equipment such as pumps and compressors, due to the new carbon fiber The grade can provide good dimensional stability and high chemical resistance, heat resistance and abrasion resistance, making it easier to manufacture.
Compared with glass fiber reinforced polyamide (PA), this carbon fiber reinforced PPA also exhibits a lower weight and a higher tensile modulus. PPA reinforced by 20 wt% carbon fiber is about 20% lighter than PA6 or PA66 filled with 50% glass fiber, while the tensile strength of 20% carbon fiber reinforced Ultramid® Advanced is better than or equal to that of 50% glass fiber reinforced polyamide. At the same time, it also showed better processability. For example, N3HC8 is very stable after high temperature aging: after heat aging at 120°C for 5000h or at 150°C for 3000h, it still maintains nearly 100% tensile modulus.
