Poly aryl ether ether ketone (PEEK) is one such engineering polymer.
Little work has been published with regards to the flammability of PEEK and its filled composites.
The current study aims to assess the flammability and fire behaviour of PEEK and its composites using thermogravimetric analysis, pyrolysis combustion flow calorimetry, limiting oxygen index, a vertical flame resistance test, and fire (cone) calorimetry. 1.
Introduction Applications in which polymers are replacing traditional materials are on the increase.
In many cases, polymers and their composites are now being used where the fire risk scenario is dissimilar to any encountered previously.
In addition to ignition resistance and low heat release rate, engineering polymers may now be required to resist burn-through and maintain structural integrity whilst continuing to provide fire protection when exposed to fire or heat. Aryl poly ether ether ketone (PEEK) is an engineering thermoplastic first introduced by Imperial Chemical Industries (ICI) in 1978 [1].
Its excellent thermal, chemical and mechanical properties have allowed for its use in a variety of high performance applications: the polymer has recently been adopted in the aviation and automotive industries where conventional thermally durable materials, such as metals, are being replaced by lighter weight, high thermal stability polymers [2] [3] [4].
To date, little work has been published on the flammability of poly(aryletherketones) with more attention a....
