Features and applications
The key features of High Strength Carbon Fiber Boards are their dense build and powerful load capacity. With thicknesses up to 50mm, they can handle extremely high compressive and bending loads. Their rigidity ensures minimal deformation, making them ideal for structural and support components-an advantage unmatched by thin sheet materials.
These boards also offer excellent machinability, suitable for drilling, milling, and turning complex shapes. Their fatigue resistance is significantly better than that of metals, offering longer service life under cyclic loading.
Applications include:
Aerospace: Used for wing spars, fuselage frames, landing gear supports-lightweight yet structurally sound.
Machinery Manufacturing: Ideal for machine tool beds, rails, and support frames-enhancing vibration damping and precision.
Automotive: Applied in chassis reinforcements, crash beams, and battery tray bases-improving safety and reducing weight.
Construction Reinforcement: Used for bridges and building beams/columns-lighter and more durable than steel plates.
Shipbuilding: Employed in hull structures and deck supports-ensures strength while improving cargo capacity.
We regularly fulfill custom orders for heavy-duty parts, from 5mm brackets to 40mm mechanical bases, precisely manufactured per customer drawings and machining specifications.
Detail introductions
Our High Strength Carbon Fiber Boards use a hybrid lay-up of unidirectional fibers and twill weave, balancing directional strength and multidirectional performance. The surface is defect-free with no pores or delamination, and a clear tapping sound indicates dense internal structure. Flatness across large areas is controlled within 0.2mm.
Thickness uniformity is tightly managed with precision pressing technology-tolerances within ±0.1mm. Edges are clean-cut and firmly bonded, even at 25mm thickness with no delamination. Drilling tests confirm excellent machinability without tearing or delaminating.
Load Testing:
Compression: Withstands extreme compressive forces without damage.
Bending: Even thinner boards withstand high bending loads; flexural modulus exceeds 130GPa.
Impact: Absorbs large amounts of impact energy without permanent deformation, outperforming metals.
Thermal Performance: Maintains mechanical strength in high temperatures, with a Tg (glass transition temperature) above 180°C-superior to many engineering plastics. In long-term load tests (50% max load over 6 months), deformation increased by less than 3%-proving excellent durability.

Attentive Service
Choosing SYCarbonFiber means worry-free solutions for your structural component needs. Our engineers begin by analyzing your application to optimize strength, weight, and cost-effectiveness.
During the design phase, we advise on ideal thickness, fiber orientation, and machining techniques. Once samples are produced, we assist with mechanical performance testing.
We offer a 12-month warranty. If strength, delamination, or cracking issues occur under normal use, we will remake the product free of charge. We also support post-processing challenges such as drilling, milling, and surface finishing.
Professional Advice Issues
Q: We require a machine base over 25mm thick. Can you ensure structural strength?
A: Absolutely. Our boards can go up to 50mm. For machine bases, we use high-strength fibers and special thick board forming methods to ensure compressive strength exceeds 1000MPa. We can optimize structure design based on your load and vibration conditions.
Q: Can High Strength Carbon Fiber Boards be machined? Will drilling or milling cause damage?
A: Yes, our boards are fully machinable. Their superior thickness makes them ideal for structural components. With proper tools (e.g., carbide cutters) and stable feed rates, there's no risk of delamination. We can also provide machining or deliver ready-to-use parts.
Q: How's the impact resistance? We need strong shock absorption.
A: Our boards reach impact strength of 250kJ/m²-much higher than metals. For shock-heavy uses, we apply tougher resin systems and optimized fiber architecture. Custom impact-resistant versions are also available.
Q: What about dimensional stability after machining?
A: Our internal stress control and curing process ensure superior dimensional stability, with minimal post-processing deformation. We also offer stress-relief treatment and finishing services for high-precision needs.
Q: How's your lead time and consistency for bulk orders?
A: With a dedicated thick-board production line, typical lead time is 10–20 business days. We ensure strength variation stays within 5%. For large orders, we offer line-specific production with FAI, mid-process, and final inspections.
Company news
SYCarbonFiber has recently made a major breakthrough in heavy-duty carbon board technology by developing ultra-thick 60mm High Strength Carbon Fiber Boards. These maintain top-tier mechanical properties with a more compact internal structure-perfect for heavy machinery and large structural parts.
We also commissioned a new ultra-large hot press, increasing maximum board size to 1.2m x 4m-supporting a broader range of industrial applications.
