Polyetheretherketone (PEEK) has gained interest in many industrial applications due to its high strength-to-weight ratio, excellent heat tolerance and high corrosion resistance. Stress concentrators such as notches and geometrical discontinuities are present in many such components necessitating the reliable assessment of notch sensitivity of PEEK in monotonic tension. Here we evaluate the appl...

This paper addresses the sensitivity of ultrasonic welding process for joining dissimilar composites to variations in either force or amplitude vibrations. For that, carbon fibre (CF)/epoxy specimens were welded CF/polyetheretherketone (PEEK) specimens, through a polyetheretherimide (PEI) coupling layer co-cured with CF/epoxy material. It was found that reducing vibrations caused an increase he...

Polyetheretherketone (PEEK) is an alternative biomedical polymer material to traditional metal and ceramic biomaterials. However, as a bioinert material, its wide application in the medical field seriously restricted due lack of bioactivity. In this research, pure Mg was successfully deposited on PEEK substrate by vapor deposition improve antibacterial properties implants. The morphology elemen...
