The strain rate sensitivity of the mechanical properties of amorphous PEEK films significantly depends on the analyzed strain rate range: i.e., 1) from 105 to 10 s1, the strain rate dependence of both apparent Young's modulus and yield stress is weak; and 2) from 101 to 200 s1, b...
However, the performance of PEEK in real downhole conditions remains unknown. In this study, we therefore investigated the evolution of the microstructural, chemical, and mechanical properties of PEEK subjected to hydrochloric acid (HCl), which is the main acid used in downhole applications, at ...
The mechanical properties of PEEK 450G have been extensively investigated. The compressive properties were measured at strain rates between 1 × 10 4 and 3000 s 1 and temperatures between 85 and 200 °C. The tensile properties were measured between the strain rates of 2.7 × 10 5 and 1.9 ×...
The mechanical properties of PEEK 150P polymer and APC-2 graphite/PEEK com posite were measured at different crystallinities, from 0 to 40 weight percent. For PEEK 150P the tensile, compressive, and shear properties and the fracture toughness were measured. For APC-2 the mode I and mode II...

Furthermore, the local viscoelastic properties of the crystalline and amorphous phases were decoupled by performing thermal CR〢FM array mapping near the glass transition temperature of PEEK (Tg, 143 °C). A distinct bimodal distribution of tip﹕ample interaction was observed for PEEK near its Tg,...
The mechanical properties of insert-molded poly(ether imide) (PEI)/carbon fiber poly(etheretherketone) (CF PEEK) have been examined. Bimaterial composite specimens were constructed by injecting CF PEEK into a mold containing one-half of a PEI tensile specimen. These PEI/CF PEEK composites retain...
The mechanical properties of carbon fiber/polyetheretherketone (CF/PEEK) composites have been characterized for structural applications. Stiffness and strength properties were measured on unidirectional laminates in tension, compression, and flexure, enabling the elastic constants for the material to be determ...

The main aim of this research was to investigate the influence of different processing temperatures on the properties of pure poly-ether-ether-ketone (PEEK). In order to do this, we used a variation of compression moulding, which enabled us to use different processing temperatures, including temp...
