It has a high melt and glass transition temperatures (Tm = 340 oC, Tg = 143 oC), high chemical resistance and is melt processable. Thus it has been used in a variety of structural and insulation applications. Nowadays, one of them is the biomedical application. The mechanical properties of PEEK have been extensively investigated in many research papers. However, there is not so high number of papers devoted to the fracture susceptibility of PEEK-material. Therefore, the the aim of this work is to present the results of studies on PEEK material with the use of fracture toughness test and digital image correlation. In order to conduct the tests, there were used two types of samples: SENB and CT. In comparison with other polymeric materials subjected to biomedical application, PEEK material presents relatively good fracture resistance with their biocompatibility.<\/jats:p>","DOI":"10.3846\/2029882x.2017.1417062","type":"journal-article","created":{"date-parts":[[2017,12,21]],"date-time":"2017-12-21T21:01:32Z","timestamp":1513890092000},"page":"207-213","update-policy":"http:\/\/dx.doi.org\/10.3846\/est_policy","source":"Crossref","is-referenced-by-count":3,"title":["FRACTURE RESISTANCE ANALYSIS OF PEEK-POLYMER"],"prefix":"10.3846","volume":"9","author":[{"given":"Grzegorz","family":"LESIUK","sequence":"first","affiliation":[{"name":"Politechnika Wroclawska, Department of Mechanics"}]},{"given":"Aleksandra","family":"SAWICKA","sequence":"additional","affiliation":[{"name":"Politechnika Wroclawska, Faculty of Mechanical Engineering"}]},{"given":"Jos\u00e9","family":"CORREIA","sequence":"additional","affiliation":[{"name":"Universidade do Porto Faculdade de Engenharia"}]},{"given":"Roman","family":"FR\u0104TCZAK","sequence":"additional","affiliation":[{"name":"Nobo Solutions S.A."}]}],"member":"2209","reference":[{"key":"CIT0001","unstructured":"ASTM D5045-14 Standard test methods for plane-strain fracture toughness and strain energy release rate of plastic materials.
