Carbon Fiber Filled Polypropylene PP 30 CF Pellets

– Composition

– Polypropylene (PP)：Acting as the base material, it makes up a significant portion within the whole composite material, roughly 70%. Polypropylene is a thermoplastic resin that is formed by the polymerization of propylene. It possesses characteristics like being lightweight, non-toxic, odorless, and having good resistance to chemical substances. Moreover, it is relatively inexpensive and widely accessible.
– Carbon Fiber (CF)：With a content of 30%, it serves as the reinforcing element. Carbon fiber is a high-strength and highly rigid fibrous substance composed of carbon atoms. It exhibits excellent mechanical attributes such as high strength, high modulus, and low density. Its strength is several times greater than that of steel, while its density is only a fraction of that of steel.

– Main Performance Characteristics

– Mechanical Properties：

– Strength Augmentation：The incorporation of carbon fiber markedly boosts the strength of the material. In comparison to pure polypropylene, the strength of polypropylene filled with 30% carbon fiber is considerably enhanced, allowing PP 30 CF to bear larger loads. It is apt for application scenarios where there are high demands on material strength, like automotive components and mechanical structural parts.
– Rigidity Enhancement：Carbon fiber has a high level of rigidity. Once filled into polypropylene, PP 30 CF intensifies the rigidity and hardness of the material, making it less susceptible to deformation and endowing it with better dimensional stability.

– Thermal Properties：

– Heat Resistance Improvement：Polypropylene by itself has a certain degree of heat resistance and can be utilized above 100°C. Carbon fiber has excellent thermal stability and can maintain good performance even at high temperatures. Consequently, the heat resistance of polypropylene filled with carbon fiber is further enhanced, enabling it to be used in higher temperature environments.
– Reduction of Thermal Expansion Coefficient：Carbon fiber has a low thermal expansion coefficient. When combined with polypropylene, it lessens the overall thermal expansion coefficient of the material, causing its dimensional changes to be smaller during temperature fluctuations. This improves the dimensional stability and reliability of the material and is suitable for applications with high requirements for dimensional accuracy, such as electronic device casings.

– Other Properties：

– Conductivity Enhancement：Carbon fiber has good electrical conductivity. A small amount of carbon fiber can confer a certain level of conductivity on the originally insulating polypropylene, which can be applied in situations where conductivity or anti-static properties are required, such as electronic packaging and anti-static materials.
– Weight Reduction Outcome：Although carbon fiber is added, due to its low density, the overall density of the material is still relatively low. On the premise of ensuring strength and performance, PP 30 CF accomplishes lightweighting, which helps to reduce the weight and energy consumption of products, meeting the demands of modern industry for lightweight materials.
