Polyether ether ketone (PEEK) is a very common thermoplastic polymer because of its mechanical characteristics; it has a very high durability under the conditions of high temperature. Through comparing the composites to unfilled PEEK, the degree of crystallinity related to PEEK resin with the addition of NPs is investigated via XRD. The composites are polycrystalline with peaks (110), (111), (220), and (213). Varieties of the modifications are carried out in the PEEK matrix through the incorporation of a variety of the nanoparticles of zirconia powders (100 nm), which added four percentages (1, 3, 5, and 7) % wt. to the polymer matrix. This project summarizes the effect of zirconia nanoparticles on green (0.9-1.7 g/cm³) bulk and (1.2-1.5 g/cm³) theoretical densities, apparent porosity (82%-84%), and Shore hardness (55-80), which are shown to improve with an increase in powder percentage.
