The disk brake may be a device for slowing or stopping the rotation of a wheel while it's in motion. A brake disc is usually made from forged iron, but in some cases, it is often made from composite materials like carbon-carbon or ceramic matrix-reinforced composites. This is connected to the wheel axle.

Another advantage of composite teeth is that they can be easily repaired if they are broken or damaged. If you use composite material only for the appearance of your teeth, in this case there is no need to grind the teeth. Also, the cost of composite teeth is much lower than other methods used to whiten and improve the appearance of teeth.

Disadvantages of Composite Fillings Among the most common disadvantages: • Durability: Composite fillings, when well cared for, can last between 7 and 10 years, while amalgams last up to 50 years in the mouth. • Hydrophobic: Composite fillings cannot get wet while they are being made; otherwise they do not adhere to the tooth. In short ...

The cost of making polymer composites and forming them into useful products is the primary disadvantage. Polymer composites are manufactured by a laborious process known as lay-up that slows down production rates, making the products less cost-effective for high production volumes. Advanced polymer composites are likewise expensive to manufacture.
