Carbon Fiber Block & Billet for CNC Machining

Carbon fiber block (also referred to as a CFRP billet) describes a solid composite form intended for subtractive CNC machining, rather than thin sheets or panels. This material form is selected when parts require sufficient machining allowance, stable internal structure, and controlled surface quality.

Our carbon fiber blocks are commonly used for precision-machined components such as knife handles and watch cases. We supply both laminated carbon fiber blocks (multi-ply consolidated billets) and forged carbon fiber billets (random marbled texture), with specifications confirmed prior to production.

If you are evaluating carbon fiber blocks for CNC machining, share your drawings or requirements with our team for a technical review.


Key Benefits for Machined Parts

  • Machinable billet form: Provides sufficient machining allowance for deep milling, drilling, and complex 3D contours.
  • Stable consolidation: Designed to minimize internal inconsistencies that may affect machining behavior.
  • Strength-to-weight advantage: Suitable for lightweight, rigid components where mass reduction matters.
  • Premium carbon aesthetics: Woven laminate appearances (e.g. 3K / 12K) or distinctive forged textures that remain visible after finishing.
Engineering note: Requirements involving elevated temperature or chemical exposure depend on the selected resin system, curing conditions, and service environment. If these factors are critical to your application, please specify them during quotation.

Target Applications

  • Knife Handles: CNC-machined handle blocks providing low weight, rigidity, and a premium tactile feel.
  • Watch Cases: Carbon fiber billets suitable for intricate 3D machining and cosmetic surface control.
  • Precision Machined Components: Custom parts where material form stability and appearance consistency are required.

Material Options & Customization

3K / 12K Laminated Carbon Fiber Blocks

Classic woven laminate structures selected for parts requiring a directional fiber appearance and controlled surface aesthetics.

Forged Carbon Fiber Billets

Random forged textures offering a non-directional, high-end visual effect. Each billet has a unique pattern; exact visual repetition is inherently limited.

Colored Carbon Fiber Blocks

Colored appearances achieved through specialized surface or fiber treatments. Available colors include black, red, blue, gold, silver, purple, and custom options.

Cosmetic reality check: Machining contours and edges may expose internal laminate layers. If edge appearance or specific “visible faces” are critical, please clearly indicate cosmetic surfaces on your drawing.
