Material Composition
Distinct layers combine to create materials stronger than their individual parts
6 days ago
0
Why do composite materials retain distinct properties from their constituent materials rather than blending into a uniform substance?
Because the materials chemically react to form a new uniform compound.
Because the materials dissolve completely into each other forming a solid solution.
Because the constituent materials remain separate and distinct within the composite, preserving their individual properties.
