High Quality & Durability 3K Flat Carbon Fiber Sheet - 3mm Thick (400x500mm)

LIJIN carbon fiber is known for its extremely high quality, durability, and beautiful finish. Each carbon fiber sheet goes through a meticulous QC process, ensuring that there are no flaws in any sheet that is sold.

These high quality carbon fiber sheets come in various thicknesses, made from 100%, 3K plain weave carbon fiber and finished with a matte surface on both sides. Unlike many low-cost carbon sheets that are made by pressing two outer skins of carbon fiber over a carbon and resin core, these plates are made with layered sheets of carbon fiber and resin, making them the same strength all the way through.

Whether you're making your own drone frames, car chassis, firewalls, bulkheads or any other custom designs that require high strength, lightweight material, these quality carbon fiber sheets are more than up to the task.

Flat Carbon Fiber Sheet is a high-performance composite panel made from premium carbon fiber fabric and epoxy resin, cured under high temperature and pressure. It offers exceptional strength, rigidity, and lightweight performance, making it ideal for structural and cosmetic applications across industrial, automotive, and aerospace fields.

Flat Carbon Fiber Sheet combines ultra-lightweight construction with outstanding mechanical strength and corrosion resistance. Featuring a smooth, flat surface with consistent thickness, it is suitable for CNC machining, cutting, drilling, and bonding. Available in multiple thicknesses, weaves, and finishes to meet custom project requirements.

Manufactured using compression molding or autoclave processes, Flat Carbon Fiber Sheets provide excellent dimensional stability, low thermal expansion, and superior fatigue resistance. Compared with metal sheets, they significantly reduce weight while maintaining high stiffness and durability.

Lightweight, high-strength flat carbon fiber sheet with excellent rigidity, corrosion resistance, and precision surface finish—ideal for CNC machining and custom composite parts.
