Ceramic-reinforced Pistons.
Pistons are another important candidate for ceramics but most companies aren't pursuing a solid ceramic piston. Instead, they're exploring the use of ceramic particles, whiskers, or fibers as reinforcement in aluminum alloys.
The ceramic reinforcement increases the strength and temperature resistance of aluminum, enabling manufacturers to substitute lightweight reinforced aluminum for heavy iron alloys and substantially reduce the weight of the car's pistons.
The improvements in strength and temperature capability can be quite remarkable.
For example, replacing only one-third of the aluminum with silicon carbide ceramic whiskers increased the strength of one aluminum alloy from about 10,000 psi to over 90,000 psi, acts and the alloy retained the increased strength to over 750 F (400°C)
