As a dedicated manufacturer with over two decades of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Automotive Chassis Reinforcement PC/Carbon Unidirectional Prepreg Tape. This high-strength laminate is engineered to meet the rigorous demands of modern vehicle chassis stiffening, offering superior mechanical properties while reducing overall weight. Our tape combines the durability of polycarbonate (PC) with the exceptional stiffness of carbon fiber unidirectional pre-impregnated material, providing a reliable solution for automotive aftermarket and OEM applications.
Our manufacturing facility, established in 1998, has grown to support an annual export value exceeding US$5 million, serving markets across North America, Europe, Asia, and beyond. We leverage advanced production techniques and strict quality control to deliver consistent, high-performance prepreg tapes that meet the needs of chassis engineers and performance enthusiasts alike.
Key Features & Technical Specifications
- Unidirectional Fiber Orientation – Maximizes load-bearing capacity along the reinforcement axis, ideal for targeted chassis stiffening.
- PC/Carbon Hybrid Matrix – Combines impact resistance of polycarbonate with high modulus of carbon fiber for excellent durability.
- High Strength-to-Weight Ratio – Significantly reduces chassis weight compared to traditional steel or aluminum reinforcements.
- Easy Handling & Curing – Prepreg format allows for clean lay-up; cures at 130°C–160°C via heat press or vacuum bag.
- Corrosion & Fatigue Resistant – Outperforms metal in harsh environments, extending service life of reinforced components.
- Customizable Dimensions – Available in various thicknesses, widths, and lengths to fit specific chassis profiles.
| Parameter | Value | Remarks |
|---|---|---|
| Tensile Strength | ≥ 2500 MPa | Tested per ASTM D3039 |
| Tensile Modulus | ≥ 130 GPa | High stiffness for minimal deflection |
| Density | 1.5 – 1.6 g/cm³ | Lightweight compared to steel (7.8 g/cm³) |
| Service Temperature | -40°C to +120°C | Suitable for under-hood and chassis environments |
| Fiber Volume Fraction | 55% – 65% | Optimized for strength and impact balance |
The Automotive Chassis Reinforcement Prepreg Tape is designed for applications such as subframe stiffening, strut tower braces, rocker panel reinforcement, and floor pan strengthening. Its unidirectional architecture ensures that the majority of fibers align with the primary load path, providing maximum efficiency in load transfer.
Advantages Over Traditional Materials
- Weight Reduction – Up to 70% lighter than steel reinforcements, improving fuel economy and handling.
- No Corrosion – Eliminates rust issues common with metal chassis components.
- Fatigue Life – Excellent cyclic load performance, ideal for long-term structural integrity.
- Design Flexibility – Can be cut and shaped to fit complex geometries, reducing installation time.
Our prepreg tape is supplied with a protective backing film and requires standard composite curing techniques. For best results, we recommend a vacuum bagging process with a ramp rate of 2–5°C/min and a dwell time of 30–60 minutes at the target temperature. Post-cure is optional depending on the required mechanical properties.

Frequently Asked Questions
-
What is the shelf life of this prepreg tape?
Stored in a freezer at -18°C, the tape has a shelf life of 12 months. At room temperature, it should be used within 30 days. -
Can this tape be used on curved chassis surfaces?
Yes, the unidirectional tape is flexible enough to conform to gentle curves. For tight radii, consider using multiple narrower strips. -
Do I need special tools for application?
Basic tools like a heat gun, vacuum bag, and an oven or heat press are sufficient. We can provide a detailed application guide. -
What is the recommended curing temperature?
Typically 130°C–160°C, depending on the desired glass transition temperature. Consult our technical datasheet for exact parameters. -
Is this product compatible with epoxy or polyester resins?
This is a pre-impregnated product with a proprietary PC/carbon matrix. It is not intended for additional wet lay-up resin application. -
Can I order custom width or length?
Absolutely. We offer customization for width (50mm–300mm), length (up to 200m per roll), and thickness (0.15mm–0.50mm). Minimum order quantities may apply. -
Does this tape provide any impact resistance?
Yes, the polycarbonate component enhances impact toughness, making it suitable for areas prone to stone chips or minor impacts. -
How do I compare this product to a standard carbon fiber prepreg?
Our PC/carbon hybrid offers improved impact resistance and slightly lower modulus than pure carbon, but with better damping characteristics. Ideal for chassis where both stiffness and durability are needed.
