Carbon Fiber 1K Tow Overview
1K carbon fiber tow contains 1,000 monofilaments per tow, producing the thinnest and lightest fabric weight in our carbon fiber product line. 1K is favored for applications demanding ultra-lightweight reinforcement, thin laminates, and high-quality surface finish — such as aerospace interior panels, sporting goods, musical instruments, and decorative composite parts.
