Chapter 17, Problem 17.1P

Interpretation Introduction

Interpretation:

The term 'composite' should be defined.

Concept Introduction:

Composites are formed when two or more material of different properties combines.

Explanation of Solution

Composites are formed by materials whose physical and chemical properties are different from each other. The formation of composites results in the property which alone cannot be reached by material

The properties of material through which composites are formed are divided in two main categories

1. Matrix material − it helps in supporting the relative position.
2. Reinforcement material- it helps in support the mechanical properties such as load.

For the formation of composites, matrix material is in continuous phase and reinforcement material is in dispersing phase. The individual properties and volume fraction of both the materials are considered.

Based on matrix material, the material can be polymer, metal, ceramics, and carbon.

Matrix composites are classified as polymer matrix composites, metal matrix composites, ceramic matrix composites and carbon matrix composites.

Based on reinforcement material, the material can be fibers, flakes, particulates, and microspheres.

Reinforcement composites are classified as fibers reinforcement composites, flakes reinforcement composites,flakesreinforcement composites.

Composites offer the property which cannot be achieved by matrix and reinforcement materials independently. Composites offer the following properties:

1. Light weight
2. Imparts strength
3. Resistance to corrosion
4. Flexibility of converting complex structure
5. Fatigue resistant

Composites had a wide application in engineering fields and formation of different products.

Application of composites:

1. Aerospace industries
2. Automobile industries
3. Fishing rods
4. Helmets
