However, for the fiber break mode, it decreases the impact strength. This phenomenon can be attributed to the effect of voids. The impact strength calculated from the typical formula is also affected by the initial notch length significantly, because the fracture surface in this experiment is no longer a plane.

IntroductionA renewable natural organic fibers act as reinforcing materials which are biodegradable and ecofriendly for the use of glass or carbon fiber and inorganic fillers. These fibers have advantages which are high specific strength modulus, low cost, low density, renewable organic, nonhazardous, malleable, wide availability, and relatively no abrasiveness [1].

Lighter, Better

If you get a rock jammed up between the OD of the rotor and the caliper for example, you can tend to damage a carbon fiber rotor. If they get impacted in the wrong way with debris you can tend to crack a carbon fiber rotor, and this rotor in that regard is much more durable than a carbon fiber rotor and again probably about half the price.
