Question

write down mechanical property and application of polymer,ceramics,and composite

Answer 1

From a chemical viewpoint, we define ceramics in terms of what they're not. So you'll find most science textbooks and dictionaries telling you ceramics are nonmetallic and inorganic solids (ones that aren't metal or based on carbon compounds); in other words, ceramics are what we're left with when we take away metals and organic materials (including wood, plastics, rubber, and anything that was once alive).
Applications of Polymers. Polymer testing and consultancy for plastics, additives with applications including aerospace, automotive, electronics, packaging and medical devices
