Sulfoanted poly(ether ether ketone) membranes were prepared by the sulfonating agent sulfuric acid. These membranes were modifed by incorporating conducting polymer polypyrrole in order to increase the ionic conductivity and reduce the methanol transmission rate. The modifed composite membranes were then compared on the basis of ionic conductivity, methanol transmission...

Compared to conventional sheet forming operations, incremental (ISF) is a flexible technique that can achieve higher formability in terms of localized deformation. Due excellent mechanical properties and X-ray penetration, polyether-ether-ketone (PEEK) an ideal alternative titanium alloy stainless steel orthopedic applications. In this study, 3-axis desktop manufacturing system has been fabrica...

A major limitation of carbon fibre-reinforced polymers is their unsuitability for repair and recycling processes due to the common employment thermoset resin matrices continuous fibres. Advanced thermoplastic discontinuous fibre moulding compounds (DFMCs) now offer an alternative high-performance components. Although DFMCs cannot match raw performance reinforcement, compression-moulding techniq...
