Frequently Asked Questions

What is the minimum order quantity for carbon fiber products?
We accept small-batch customization. Minimum quantities vary by product type — tubes and plates have lower MOQs, while custom-shaped parts depend on tooling requirements. Contact our sales team for a detailed quote.
What color and finish options are available?
Standard finishes include 3K plain/twill weave, UD unidirectional, and satin, primarily in black. Custom colors and surface coatings — including matte and gloss clear coats — are also available.
What is the typical lead time?
Standard product lead time is 15–25 working days. Custom products are evaluated based on process complexity. Rush service is available — please confirm timelines when requesting a quote.

Introduction Every wind turbine blade eventually becomes a disposal problem, and the first industrial step of that problem is dismantling and pre-processing. A modern blade is 60-115 meters long, weighs 20-40 tonnes and is built from a mix of glass fiber, carbon fiber, epoxy, balsa and adhesives. It

Wind Sector Carbon Fiber Demand: 100,000 Tonnes in 2025, China Top Supplier and the 2030 Demand Trajectory

Introduction Wind energy is now the largest single demand sector in the global carbon fiber market. Industry estimates put wind-sector consumption at roughly 100,000 tonnes in 2025, ahead of aerospace, pressure vessels and automotive. The driver is simple: blades keep getting longer. When a blade pa
