Carbon Fiber vs. Fiberglass


Carbon fiber composites are roughly 15% lighter than fiberglass composites, 40% lighter than aluminum, and 70% lighter than steel. The majority of weight-critical performance items are made from carbon fiber because of its extremely light, stiff, and robust nature.

Strength and Flexibility

Both carbon fiber and fiberglass exhibit excellent strength-to-weight ratios and are exceptionally strong materials. When deciding between carbon fiber and fiberglass, stiffness of the intended product is frequently a deciding factor. Carbon fiber is the ideal material for uses where a small level of flexibility is required. The ultimate breaking point of fiberglass is greater than that of carbon fiber for situations where a great deal of flexibility is required. Carbon fiber has a relatively narrow flex window, whereas fiberglass is better adapted to high flex patterns.


Carbon fiber with long fibers are expensive and complex to create, but fiberglass manufacturing is significantly simpler. Fiberglass is therefore far less costly than carbon fiber.

Carbon Fiber / Fiberglass

Some parts need carbon fiber's strength while still appealing to a wide market at a low cost. In order to get the distinctive properties of each fiber option, while staying within cost limits, we can combine fiberglass and carbon fiber in the same part so that you still get the look of carbon fiber at a lower cost.
