Answer 1

Explanation:

Typical engineered composite materials include: Reinforced concrete and masonry. Composite wood such as plywood. Reinforced plastics, such as fibre-reinforced polymer or fiberglass

Answer 2

Question:

Which of the following is a composite material?

1. Y-alloy
2. High speed steel
3. Tungsten carbide
4. Fiber reinforced plastic
5. None of the above

Answer:

High speed Steel (2)

Explanation:

• A composite material is a material made from two or more components. These constituent materials are grouped together to create materials that have different chemical or physical properties, especially those of individual elements. Within the final structure, the individual elements are separated and distinguishable, distinguishing the composite from mixtures and solid solutions.
• High-speed steel is an alloy that derives its properties from various alloy metals added to carbon steel, usually containing tungsten and molybdenum, or a combination of both, often combined with other alloys. So, it is a composite material.
