Carbon Fiber vs FR-4 and G10: Choosing the Right Composite Sheet
A simple comparison of carbon fiber, FR-4, and G10 for stiffness, insulation, finish, and project fit.
Carbon fiber
Carbon fiber is usually chosen when high stiffness, low weight, and premium visual finish are important.
FR-4 and G10
FR-4 and G10 are useful where insulation, dimensional stability, and cost-effective composite performance matter.
Project fit
The right material depends on strength, weight, insulation, environment, machining, quantity, and budget.
