Meta Aramids were invented by Willford Sweeney a Dupont chemist in the very early 60’s.
It was when he returned from a weekend he discovered this material at the top of a vat.
Curiously he worked with the fibrous material not thinking a lot about it.
Then in the early ’60s Racing was encountering tragic deaths by fire, a solution was needed.
After more experiments, the fibrous material was made into a filament and it was discovered that it was flame retardant.
Meta Aramids descend from Nylon 66 a petroleum-based product. So it was a unique discovery that something generally so flammable would not easily ignite.
Meta Aramids are now routinely used where the material is subjected to heat.
