What’s PPA LCF20?

PPA LCF20 refers to a polyphthalamide (PPA) material reinforced with 20% long carbon fiber (Long Carbon Fiber).

PPA is a thermoplastic functional nylon with both semi-crystalline and amorphous structures. It has excellent comprehensive properties in terms of heat, electricity, physics, and chemical resistance. In harsh working environments such as high temperature, humidity, oil stains, and chemical corrosion, it still has excellent mechanical properties, including high rigidity, high strength, high dimensional accuracy, low warpage and stability, fatigue resistance, and creep resistance.

The addition of 20% long carbon fiber can further improve the strength, rigidity, wear resistance and other properties of PPA, making it applied in some fields with high requirements for material properties, such as automobiles, aerospace, electronics and electrical appliances.

PPA LCF20% materials produced by different manufacturers may have differences in specific properties and applications. If you need more accurate and detailed information about it or other long carbon fiber filled nylon composites, it is recommended to consult us.

Which advantages PPA CF20 has compared with other carbon fiber reinforced composites?

1. Superior comprehensive performance: PPA on its own has outstanding comprehensive properties in aspects such as heat, electricity, physics and chemical resistance. When combined with long carbon fibers, its mechanical characteristics are even more remarkable in harsh environments.
2. High strength and rigidity: The combination of the PPA matrix and carbon fiber is excellent, enabling it to withstand greater loads and stresses.
3. Exceptional wear resistance: Compared to other materials, it has a longer service life in a frictional environment.
4. Low specific gravity: While maintaining performance, it is lighter in weight, which is beneficial for lightweight applications.
5. Good processability: PPA is easy to process. After adding long carbon fibers, it still retains good processability.
6. Excellent long-term stability: In long-term use, its performance remains stable, reducing maintenance costs.
7. Good fatigue resistance: Under repeated loads, it exhibits higher durability and reliability.

The performance of different carbon fiber reinforced plastics varies significantly. The advantages of PPA LCF20 need to be evaluated based on actual applications. Moreover, products from different manufacturers may have different performances. If accurate information is required, one can refer to its technical datasheet or consult us.

Case – PPA LCF20 Applied in Engine Components

PPA LCF20 is applied in the manufacturing of engine components, specifically intake manifolds.

Traditional intake manifold materials may gradually degrade, deform, or even fail in high-temperature, vibration, and chemically corrosive environments. In contrast, intake manifolds made from PPA LCF20 offer several significant advantages:

1. Its exceptional thermal performance enables it to function reliably in the high-temperature environment of the engine bay without softening or deforming. With a heat deflection temperature reaching [specific temperature value], it far surpasses that of standard materials.

2. The addition of 20% long carbon fiber imparts the intake manifold with high strength and rigidity. Under the constant vibrations of the engine, it maintains structural integrity without cracking or loosening. Additionally, its high dimensional accuracy ensures precise fitment with other engine components, enhancing overall engine performance and reliability.

3. PPA LCF20 exhibits excellent chemical resistance, capable of withstanding the corrosive effects of fuel, lubricants, and other substances within the engine, thereby extending the intake manifold’s service life.

4. Compared to traditional metal intake manifolds, PPA LCF20’s low specific gravity contributes to reducing the overall weight of the vehicle, improving fuel efficiency. Moreover, its excellent processability makes production more efficient, lowering manufacturing costs.

By being applied to automotive engine intake manifolds, PPA LCF20 demonstrates its great potential in the high-performance materials sector, providing new solutions for the automotive industry’s development.
