Final answer:
Ceramic-matrix composites are stronger than traditional ceramics like porcelain due to the toughness and strength provided by reinforcing fibers.
Step-by-step explanation:
When considering the strength of materials, it's important to understand that ceramics by themselves are typically strong but can be brittle. Ceramic-matrix composites, on the other hand, which are ceramics reinforced with fibers, tend to be stronger than traditional ceramics like porcelain alone. These composites benefit from the combination of materials where the reinforcing fibers provide toughness and strength to the ceramic matrix, allowing the material to withstand higher stress without fracturing. This makes the combination of metal and ceramic in a composite more resilient than porcelain, which is a type of ceramic, on its own.
