Question

in which material composite, metal, polymer, ceramics have high strength

Answer 1

Answer:

1. Composites have a high strength-to-weight ratio.

Perhaps the biggest advantage of composites is their high strength-to-weight ratio. Carbon fiber weighs about 25% as much as steel and 70% as much as aluminum, and is much stronger and stiffer than both materials per weight. High-end auto engineers use composites to decrease vehicle weight by as much as 60% while improving crash safety; multilayer composite laminates absorb more energy than traditional single-layer steel. Harnessing the power of composites benefits manufacturers and consumers alike.
