Material Composition and Content

PBT CF5 is a thermoplastic composite that is reinforced and modified by incorporating 5% carbon fiber into polybutylene terephthalate (PBT) as the base material. The amount of carbon fiber is precisely adjusted to notably enhance the material’s performance without a substantial increase in material cost.

Main Performance Advantages and Application Cases

1. High strength: The strength is significantly improved compared to ordinary PBT materials and can be used to manufacture high-strength mechanical parts such as automobile engine brackets. Data shows that its tensile strength can reach 150 MPa.
2. High modulus: It has high rigidity and can provide better dimensional stability in applications such as electronic device casings. For example, when used for mobile phone casings, it can effectively prevent deformation.
3. Good heat resistance: It can maintain stable performance at higher temperatures and is suitable for parts around the automobile engine and can withstand ultrahigh working temperatures up to 160°C.
4. Low shrinkage rate: It has high molding precision. When used for precision electrical plugs, it can ensure accurate dimensions, and the error can be controlled within 0.05%.
5. Excellent electrical conductivity: Carbon fiber endows PBT CF 5 with a certain degree of electrical conductivity, making it applicable for antistatic products like electronic component packaging.
6. Strong corrosion resistance: PBT 5 CF performs excellently in applications such as pipeline connectors in the chemical industry and can withstand the erosion of various chemical substances.
7. Lightweight: Compared to metal materials, PBT CF5 is lighter in weight, which is beneficial for reducing the overall weight of products. For instance, it is utilized in some small parts in the aerospace field.
8. Good wear resistance: Used for transmission parts such as gears to extend service life. After testing, the wear rate is reduced by 30% compared to ordinary materials.

Case Sharing – PBT CF5 Applied in Auto Intake Manifolds

The intake manifold of a car engine is an important part for the normal operation of a car. Traditional materials are prone to deformation under high temperatures and complex working environments, affecting engine performance. The intake manifold made of PBT CF5 composite material, with its good heat resistance, can work stably in an environment as high as 160°C. At the same time, its high-strength characteristic enables the intake manifold to withstand the vibration and pressure of the engine, ensuring the reliability of long-term use.

In addition, the low shrinkage rate of this material ensures the precision of dimensions. The error can be controlled within 0.05%, providing a guarantee for the high-performance operation of the car. It is worth mentioning that Carbon (Xiamen) New Material, as the producer of this composite material, provides high-quality PBT CF5 materials for the automotive industry with its superb technology and strict quality control.
