Polyether ether ketone tensile strength

Reinforced polymers that combine high tensile strength with high flexural modulus include polybutylene terephthalate, polyether ether ketone, polyamide-imide, and polyethylene terephthalate (see Table 3.3). 

As seen in Table 3.1, the incorporation of 50% glass fiber into polyether ether ketone (PEEK) increased the tensile strength from 92 to 150 MPa and increased the flexural modulus from 3.7 to 10.3 GPa, while decreasing the elongation at break from 50% to 2.2%. 

Polyether ether ketone s excellent hydrolysis resistance is documented by its entirely unchanged tensile strength after 200 days of exposure to boiling water. Polyether ether ketone went through hydrolysis tests at 280 °C and 18 bar without damage [723], Thanks to its good high-temperature and chemical resistance, polyether ether ketone is suitable for hot-steam sterilization [985]. 

Aromatic polymers have many desirable properties such as good lap shear strength, thermal stabihty, and tensile strength, which make them useful for a wide variety of applications. The term aromatic polymer is used herein to mean a polymer, which has aromatic groups incorporated in the repeat unit of their backbone chain. Such polymers include polyimides (Pis), polyetherimides, polysulfones, polyether sulfones, polyaryl ether ketones, polycarbonates, poly-arylates, and the like [20].
