The understanding of fracture mechanisms and the assessment toughness are key factors to design high-performance composite structures be used in aeronautics. Thus, this work addresses influence initial notch orientation on translaminar woven-ply hybrid fibers reinforced thermoplastic polyether ether ketone (PEEK) laminates. Single-edge-notch bending (SENB) specimens is experimentally characteri...

Structures made of the thermoplastic polymer polyether ether ketone (PEEK) are widely used in dynamically-loaded applications due to their high-temperature resistance and high mechanical properties. To design these dynamic applications, addition well-known stiffness strength properties vibration-damping at given frequencies required. Depending on application, from a few hertz ultrasonic range i...

Abstract The goal of this work is to evaluate the potential diamond-like carbon (DLC) coatings on thermoplastic polymers for friction and wear reduction in highly stressed rolling–sliding contacts. Therefore, hydrogen-containing DLC were deposited polymer surface by a low-temperature high power pulsed magnetron sputtering (HPPMS) physical vapor deposition (PVD) process. rolling-sliding contact ...

Polyether ether ketone (PEEK) possesses excellent mechanical properties similar to those of human bone and is considered the best alternative material other than titanium for orthopedic spine and trauma implants. However, the deficient osteogenic properties and the bioinertness of PEEK limit its fields of application. The aim of this study was to limit these drawbacks by coating the surface of ...

Amaç: Servikal disk hernilerinde altın standart tedavi yöntemi olarak kabul edilen anterior servikal diskektomi ve içi demineralize kemik matriks ile dolu polyether-ether-ketone (PEEK) kafes füzyon uygulanan hastaların cerrahi sonuçları değerlendirilerek, günümüzde popüler olan artroplastisi gibi tekniklerle literatür taraması eşliğinde karşılaştırılmıştır. Gereç yöntem: Ağustos 2011 Nisan 2015...

The 3D printing technology used for small tidal and wind turbines has great potential to change overcome certain weaknesses in traditional manufacturing techniques. In rural areas isolated communities, turbine systems could be locally fabricated assembled by using additive machines also can employed decrease residential energy consumption. objective of the paper is study thermomechanical perfor...
