What is Kevlar, and why is it so popular?

What is Kevlar, and why is it so popular?

Invented by DuPont in 1965, this incredible super strong synthetic yellow material originally came about to find a replacement for lighter and stronger tyres.

5 times stronger than steel on a weight to weight basis, it's probably the toughest fibre you can buy that can take an incredible pounding. This then was quick to be adopted by many other industries, motorsport being one of them.

Bullet proof vests made from the same material is also why this is used extensively all over rally cars, as seen here on Andreas Mikkelsen's Hyundai.

Wheel arches, sills, fuel tanks and sump guards are some of the prone areas for damage from projectile stones.

Difficult to work with because of the strength of the individual fibres even in its cured state, sanding it will go frayed and furry, then trying to cut it can be very time consuming and soul destroying, using a oscillating saw can achieve quicker results.

For the furry ends, apply a little superglue or resin, then wait for it to cure, before trimming it down again.
