Why can a feather-like Thin Carbon Fiber Plate be used in precision instruments, while a massive Thick Carbon Fiber Plate withstands tons of pressure?
Carbon fiber-this high-performance material dubbed "black gold"-has transitioned from a luxury in aerospace to an everyday essential. From sports car bodies to smartphone cases, its presence is undeniable. But have you ever wondered how these seemingly simple carbon fiber products, especially distinct forms like Thin Carbon Fiber Plate and Thick Carbon Fiber Plate, are actually manufactured?
1,From "Black Thread" to "Black Gold": The Alchemy of Carbon Fiber
The core raw material for carbon fiber is polyacrylonitrile (PAN) precursor. Through pre-oxidation, carbonization, and graphitization, non-carbon elements are stripped away, forming a crystalline structure with over 90% carbon content.
Key Process for Thin Carbon Fiber Plate
For lightweight, high-precision Thin Carbon Fiber Plate (e.g., drone frames or electronic brackets), dry-jet wet spinning is used. This technique produces finer, more uniform fiber tows. Unidirectional prepreg layers are then low-temperature molded into plates as thin as 0.2-1mm.
Strength Secret of Thick Carbon Fiber Plate
Thick Carbon Fiber Plate (e.g., wind turbine beams or structural components) requires stacking large-tow carbon fiber fabrics. Resin transfer molding (RTM) injects resin under high pressure, followed by high-temperature curing to eliminate voids, achieving plates over 10mm thick with steel-like strength.
2,Thin vs. Thick: The Technical Battle Behind Applications
While Thin Carbon Fiber Plate and Thick Carbon Fiber Plate seem opposites, they complement each other-their production differences stem from extreme performance demands.
The "Light" and "Precise" Thin Plate:
① Medical Field: Thin plates in surgical tools offer X-ray transparency and antibacterial properties, ideal for CT machine guides.
② Consumer Electronics: 0.3mm ultra-thin plates with 3D hot pressing retain aesthetic weave patterns while providing electromagnetic shielding.
The "Sturdy" and "Robust" Thick Plate:
① New Energy Sector: Thick plates in wind turbine blades use multi-axial weaving to endure 15m/s wind pressure, outperforming traditional fiberglass by 30% in lifespan.
② Rail Transit: 20mm thick plates in high-speed train noses combine lightweight design with fatigue resistance.
3. Carbon Fiber in the Market Surge: Who Leads the Wave?
According to 2025 China Carbon Fiber Industry Report, the global carbon fiber market will grow at 12% annually, with China capturing over 40%. In this boom, Thin Carbon Fiber Plate dominates consumer electronics and medical devices, while Thick Carbon Fiber Plate thrives in new energy and infrastructure.
【Yet challenges remain】:
① Cost Barriers: High-performance thin plates rely on imported precursors, keeping prices steep.
② Technical Hurdles: Thick plates require breakthroughs in resin infiltration and curing uniformity.
4. Guangdong Shenyang New Materials: 11 Years of Expertise in "Dry Carbon"
Amid industry competition, Guangdong Shenyang New Materials Co., Ltd. stands out with its commitment to "dry carbon only."
① Technical Edge: Proprietary dry molding eliminates solvent residues from traditional wet methods, boosting Thin Carbon Fiber Plate strength by 15% and achieving industry-leading 85MPa interlaminar shear strength for Thick Carbon Fiber Plate.
② Case Studies: Custom 3mm thin plates for EV battery enclosures reduce weight by 40% with IP67 certification; 8-meter thick beams for offshore wind projects operate flawlessly over 20,000 hours.
Conclusion From lab precision to factory roars, from the elegance of Thin Carbon Fiber Plate to the might of Thick Carbon Fiber Plate, carbon fiber manufacturing is a dance of technology and art. In this era of lightweight revolution, partnering with a veteran like Guangdong Shenyang-an 11-year expert in dry carbon-could be your key to future success.
