Needs , Advantages, Characteristics of Composites

NEED FOR COMPOSITES

1. As composites never rust and have less fracture toughness than metals, we need different composites.

2. To reduce maintenance cost and ensure long-term stability composites are essential.

3. It is essential because according to the needs, using different fibres and matrix, properties of composites can be modified

4. In telecommunication industries, need of power transmission along with data transmission is increasing, so composites are highly essential.

5. Composites are highly required because, of its lower weight reduces fuel consumption and emission.

6. As carbon fibre weighs about 25% as much as steel and 70% as much as aluminium and is much stronger and stiffer than both materials, we need composites.

ADVANTAGES (OR) CHARACTERISTICS OF COMPOSITES

(i) They possess higher specific strength and lower specific gravity.

(ii) They possess lower electrical conductivity and thermal expansion.

(iii) They possess better creep, fatigue strength, corrosion and oxidation resistance.

(iv) They maintain very good strength, even upto high temperatures.
