CQDJ High-Performance Carbon Fiber Sheets & Industrial CFRP Panels

carbon fiber sheet (also known as a carbon fiber plate or CFRP—Carbon Fiber Reinforced Polymer) is a high-performance composite material made by infusing carbon fiber fabric with a rigid resin, such as epoxy.

Think of it as the "steel of the 21st century," but with 5 times the strength of steel and only 1/5th of the weight.

Key Characteristics

• High Strength-to-Weight Ratio: It is the primary reason the aerospace and racing industries use it. You get maximum rigidity with minimal mass.

• Corrosion Resistance: Unlike steel or aluminum, carbon fiber won't rust or corrode when exposed to salt, water, or harsh chemicals.

• Low Thermal Expansion: It stays dimensionally stable. If it gets hot or cold, it won't warp or expand significantly, making it vital for precision instruments.

• Aesthetic Appeal: The iconic "carbon weave" look has become a symbol of luxury and high-tech performance.

Common Formats & Specs

When searching for carbon fiber sheets, you will encounter these technical terms:

Thickness: Ranges from 0.5mm (thin/flexible) to 10mm+ (thick/structural plates).

Weave Type:

3K Twill: The classic diagonal pattern seen on supercars.

Plain: A simple checkerboard pattern.

Unidirectional (UD): Fibers run in one direction for maximum strength in a single axis.

Forged: Chopped fibers pressed together for a marbled, stone-like appearance.

Finish: Glossy (shiny/reflective) or Matte (satin/dull).

APPLICATION

• Automotive: Hoods, splitters, dashboards, and chassis reinforcement.

• Drones & Robotics: Lightweight frames for FPV racing drones and robotic arms.

• Industrial: CNC-machined parts, stiffening plates, and specialized tooling.

• Marine: Decking, rudders, and high-strength bulkheads (often using 4x8 carbon fiber sheets).

• Medical: X-ray beds (because carbon fiber is radiolucent—meaning X-rays pass right through it).

PACKING AND STORAGE

At CQDJ, we ensure every carbon fiber sheet reaches you in factory-perfect condition through rigorous protection and logistics standards.

Professional Packaging

Surface Protection: Each carbon fiber panel is dual-side covered with a high-grade PE protective film to prevent scratches.

Secure Layering: Sheets are interleaved with soft EPE foam to eliminate friction during transit.

Heavy-Duty Crating: For large 4x8 sheets and bulk orders, we utilize reinforced plywood crates and corner guards to ensure zero-deformation during sea or air freight.

Storage Guidelines

Flatness: Always store carbon fiber plates horizontally on a level surface to prevent long-term warping or bowing.

Environment: Maintain a cool, dry, and shaded area (15°C–30°C). Avoid direct UV exposure to preserve the resin’s high-gloss or matte finish.

Handling: Always "lift and place" rather than slide. We recommend using lint-free gloves to avoid fingerprint oils on the composite surface.
