Poly ether ether ketone (PEEK) is a specialty plastic having many interesting physical, mechanical, electrical properties and it is resistant to most of the chemicals. Although this plastic is costly it is useful for manufacturing several niche applications such as satellite components, bio Implants and wear resistant components. This review article covers different aspects of polymer composites, hybrid composites and nano composites developed by using PEEK as matrix from 2013 to 2020. Various applications of PEEK matrix composites have also been reviewed. © 2023 Elsevier B.V., All rights reserved.
