Product Details
Extra thick carbon fiber plates deliver exceptional rigidity and structural stability for demanding industrial applications. Specifically, unlike standard carbon fiber sheets, these heavy-duty plates range from 30mm to 120mm in thickness. Therefore, they provide a solid carbon fiber block that serves as an ideal base material for CNC machining, mold tooling, and precision engineering.
Furthermore, the internal unidirectional fiber layup maximizes strength along the primary load path. Meanwhile, the outer twill or plain weave surface adds cross-directional reinforcement and a premium finish. As a result, the combination of UD core and woven surface delivers both raw strength and surface durability in one solid plate.
Additionally, our extra thick carbon fiber plates come in four carbon fiber grades. In particular, we offer T300 for general industrial use, T700 for high-performance structural requirements, T800 for advanced applications, and T1000 for specialized high-strength needs. Moreover, you can choose between glossy and matte surface finishes. Notably, standard sizes range from 500×500mm to 1200×1200mm, and we accept custom orders up to a maximum of 3000×8000mm.
In terms of the manufacturing process, the plate is built through multiple layers of unidirectional carbon fiber inside. This creates a dense and uniform core for maximum strength. After that, the outer layers use woven carbon fiber fabric in twill or plain weave pattern for surface protection and aesthetics. Consequently, these plates combine the raw strength of unidirectional carbon with the durability of a woven surface — making them suitable for applications where standard thin sheets simply cannot meet the performance requirements.

Applications
- Industrial mold tooling — Composite molding molds, vacuum forming dies, and press tooling that require extreme rigidity and dimensional stability. The lightweight nature reduces handling difficulty compared to steel molds
- Heavy machinery bases — Press machine bases, CNC machine worktables, and inspection platforms where vibration damping and load-bearing capacity are critical. Thick plates maintain flatness under heavy static and dynamic loads
- CNC machining blanks — Thick carbon fiber blocks serve as raw material for precision CNC milling into complex parts, fixtures, jigs, and custom tooling components
- Marine engineering — Ship hull base plates, bulkheads, and deck structures that benefit from corrosion resistance and weight reduction in saltwater environments
- Structural reinforcement — Bridge and building reinforcement applications where carbon fiber plates replace steel for superior strength-to-weight ratio and corrosion resistance
- Wind power components — Turbine blade roots and tower connectors that demand high load resistance and long-term reliability under cyclic loading

Production Process
First, workers select the carbon fiber prepreg based on your required grade (T300, T700, T800, or T1000). Then, they lay unidirectional carbon fiber sheets in the core to build thickness and maximize strength along the load axis. After that, woven carbon fabric is applied to the top and bottom surfaces for aesthetics and multi-directional protection. Finally, the plate is cured under heat and pressure in a hydraulic press.
- Material Selection — Choose prepreg based on your required grade
- Core Layup — Layer unidirectional carbon fiber to build thickness
- Surface Application — Apply twill or plain weave fabric to top/bottom
- Stack Assembly — Assemble complete layup in mold
- Hot Press Curing — Cure under high temperature and pressure
- Demolding — Remove the finished plate from mold
- Surface Finishing — Sand and coat for glossy or matte finish
- Quality Inspection — Verify dimensions, surface, and structural integrity
Frequently Asked Questions
What thickness range can you manufacture?
We manufacture extra thick carbon fiber plates ranging from 30mm to 120mm as standard. Thicker plates are available upon request. Our maximum thickness capability continues to expand based on customer requirements.
What is the maximum size you can produce?
Our standard sizes include 500×500mm, 600×600mm, 1000×1000mm, and 1200×1200mm. For custom orders, we can manufacture plates up to 3000×8000mm. Contact us with your specific dimensional requirements for a custom quote.
How does the internal structure differ from standard carbon fiber plates?
Extra thick plates use unidirectional carbon fiber layers in the core to maximize strength along the primary load axis. The outer surfaces feature twill or plain weave fabric for aesthetics and multi-directional protection. This construction method delivers superior load-bearing capacity compared to standard woven plates of the same thickness.
Can you CNC machine thick carbon fiber plates?
Yes, our extra thick carbon fiber plates can be precision CNC machined including drilling, milling, routing, and cutting. We use specialized diamond-coated tooling to ensure smooth edges without delamination. Send us your CAD files for a machining quote.
What carbon fiber grades are available for thick plates?
We offer T300 as the standard grade for most applications. T700 and T800 grades are available for higher performance requirements. T1000 is also available for specialized applications requiring maximum strength, though it comes at a premium cost due to the material price and processing complexity.
How much lighter is carbon fiber compared to steel?
Carbon fiber has a density of approximately 1.6 g/cm³, while steel is around 7.8 g/cm³. This means carbon fiber plates weigh about 80% less than steel plates of the same dimensions. In practical applications, this weight reduction translates to easier handling, lower structural support requirements, and improved energy efficiency.
What is the typical lead time for extra thick plates?
Standard production completes in 7-15 business days depending on thickness and size. Thicker plates require longer curing times to ensure complete consolidation. Rush options are available for urgent projects. We will confirm exact timelines when you place your order.
