Explanation:

Fibres are materials that are used to make fabrics and textiles. They can be natural or synthetic. Natural fibres are derived from plants or animals, while synthetic fibres are made from chemicals. Fibres can have different properties, such as strength, elasticity, and durability.

What is the strongest fibre?

The strongest fibre is considered to be nylon. Nylon is a synthetic fibre that was first developed in the 1930s by a team of scientists at DuPont. It is made from a polymer, which is a long chain of repeating molecules. Nylon has several properties that make it a strong fibre:

- Strength: Nylon is a very strong fibre, with a tensile strength of about 75,000 psi. This means that it can withstand a lot of force or weight without breaking.
- Durability: Nylon is also very durable, which means that it can last a long time without wearing out or breaking down.
- Resistance: Nylon is resistant to many chemicals, including oils, solvents, and alkalis. This makes it a good choice for applications where it will be exposed to harsh environments.

Other strong fibres:

While nylon is considered to be the strongest fibre, there are other fibres that are also very strong. These include:

- Kevlar: Kevlar is a synthetic fibre that is used in body armor, helmets, and other protective gear. It is five times stronger than steel and is very lightweight.
- Carbon fiber: Carbon fiber is a synthetic fibre that is used in aerospace and other high-performance applications. It is very strong and lightweight, and has a tensile strength of about 500,000 psi.
- Spider silk: Spider silk is a natural fibre that is produced by spiders. It is very strong and elastic, and is used by spiders to build webs and catch prey.

Conclusion:

In conclusion, nylon is the strongest fibre due to its high strength, durability, and resistance to chemicals. However, there are other strong fibres such as Kevlar, carbon fiber, and spider silk that are also used in various applications.

Its answer is nylon because it is the first fully synthetic fibre made by using cool air and water it is strong as nylon rope is used for parachutes and rock climbing also a nylon thread is much stronger than a steel wire.
