As a manufacturer with over 25 years of experience in advanced materials, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our PPS UD carbon prepreg – a high-performance composite material specifically engineered for aerospace structural components. This prepreg combines the exceptional thermal stability of polyphenylene sulfide (PPS) resin with the superior strength of unidirectional carbon fiber, delivering an optimal balance of lightweight performance and high stiffness. Our product is designed to meet the rigorous demands of modern aerospace applications, where weight reduction and structural integrity are critical.
Manufactured under strict quality control, our PPS UD carbon prepreg features a consistent resin content and uniform fiber distribution. The unidirectional fiber orientation provides maximum mechanical properties in the load direction, making it ideal for primary and secondary aerospace structures such as wing spars, fuselage frames, and interior panels. Compared to traditional metallic materials, this prepreg offers up to 60% weight savings while maintaining excellent stiffness-to-weight ratio.
Key Features & Technical Specifications
- High Stiffness & Strength: Tensile modulus up to 230 GPa, tensile strength up to 3500 MPa (depending on fiber type).
- Thermal Stability: PPS resin offers continuous service temperature up to 220°C, with short-term exposure up to 260°C.
- Excellent Chemical Resistance: Resistant to aviation fuels, hydraulic fluids, and most solvents.
- Low Moisture Absorption: <0.05% by weight, ensuring dimensional stability in humid environments.
- Good Processability: Suitable for autoclave, compression molding, and hot press forming.
- Customizable Options: Available in various widths, thicknesses, and roll lengths to suit specific part geometries.

Benefits for Aerospace Applications
- Weight Reduction: Directly contributes to fuel efficiency and increased payload capacity.
- Fatigue Resistance: Carbon fiber composites exhibit superior fatigue life compared to metals.
- Design Flexibility: UD prepreg allows tailored layups to optimize strength in specific directions.
- Consistent Quality: Our prepreg is manufactured with tight tolerance on resin content and fiber alignment.
- Cost-Effective: Reduced part count and assembly time compared to metallic structures.
Our PPS UD carbon prepreg is available in standard widths up to 1000mm, and can be slit to narrower widths upon request. The material is supplied on rolls with a protective PE film to prevent contamination. Customized resin formulations and fiber types (e.g., intermediate modulus, high strength) are also available to meet specific performance requirements.
Frequently Asked Questions
-
Q: What is the storage condition for this prepreg?
A: The prepreg should be stored in a freezer at -18°C or below, sealed in a moisture-proof bag. Under these conditions, shelf life is 12 months. At room temperature, the out-life is typically 30 days. -
Q: Can this prepreg be used for parts requiring high temperature resistance?
A: Yes, the PPS resin provides continuous service temperature up to 220°C, making it suitable for engine nacelle components and other high-temperature zones. -
Q: Is the prepreg compatible with automated layup processes?
A: Absolutely. The material has good tack and drape, and is suitable for automated fiber placement (AFP) and automated tape laying (ATL) processes. -
Q: What curing cycle is recommended?
A: Typical cure cycle: heat to 320°C at 1-3°C/min, hold at 320°C for 30-60 minutes under 0.6-0.8 MPa pressure, then cool down at 2-3°C/min. However, the exact cycle may vary based on part thickness and geometry. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples for qualification testing. Please contact our sales team to discuss your requirements. -
Q: What is the minimum order quantity?
A: The MOQ is typically 50 kg per specification, but smaller quantities may be considered for R&D projects. -
Q: How do you ensure quality consistency?
A: Each batch is tested for resin content, volatile content, and mechanical properties. We provide a certificate of analysis with every shipment. -
Q: Can you supply custom widths or slit rolls?
A: Yes, we can slit to widths as narrow as 50mm. Please specify your required width when placing an order.
