Carbon Fiber Fabric: Industrial Buyer Guide to Types, Specifications and Applications
Carbon fiber fabric is not a commodity. Two rolls sitting side by side in a warehouse can behave entirely differently once they go into a mold. Weave architecture, filament count, areal weight, and surface finish all determine whether a part ends up in a certified aircraft or a rejected reject bin. This guide covers what procurement engineers and composite engineers need to know before placing an order. Contents What Carbon Fiber Fabric Actually Is Weave Architecture: Choosing the Right Pattern Filament Counts: 1K, 3K, 6K, 12K, 24K Areal Weight (GSM) and What It Controls Processing Compatibility: Wet Layup, Prepreg, Infusion, Pultrusion Application Selection Matrix Carbon Fiber Fabric Products from Impact Materials Sourcing & Quality Considerations Frequently Asked Questions 1. What Carbon Fiber Fabric Actually Is Carbon fiber fabric is a woven textile produced from continuous carbon fiber tow. The fiber itself — typically PAN-based — is converted from polyacrylonitrile precursor through a sequence of oxidation, carbonization, and surface treatment steps. The resulting filaments have tensile strengths in the 3,500–7,000 MPa range, paired with densities around 1.76–1.80 g/cm³ that give it an exceptional strength-to-weight ratio over metals. When that tow is woven into fabric, a structural material emerges that can be
