Comparison of carbon fiber and glass fiber

weight

How to compare the glass fiber and carbon fiber? When compared with other composite materials, the glass fiber is not so efficient. But the glass fiber is still lighter than conventional materials (wood, steel, etc.). It is given for strength, fiberglass chopped strand mat weight demanding project, the carbon fiber will perform better.

Strength and durability

Similarly, the carbon fiber will surpass glass fiber in its tensile strength (the fiber force required to pull apart) and compressive strength (downward pressure on the fiber strength). However, the glass fibers are more "durable", you can put glass fiber close to its breaking point, but not too obvious, like carbon fiber.

Failure mode

In addition, once the carbon fiber reaches its breaking point, catastrophic failure mode (it will fracture / broken pieces.) And glass fiber, on the other hand, will produce cracks or deformation prior to fracture.

cost

Unfortunately, due to the nature of the carbon fiber, compared to other materials, he is more expensive. So, excellent strength, glass fiber weight if your item is less demanding, and will not need to come from carbon fiber is a good choice.
