Single Point Incremental Forming (SPIF) is a dieless and flexible forming technology that allows performing complex shapes presents high economic payoff for low production series. In this context, research an experimental investigation of Polyether ether ketone (PEEK) sheets deformed by SPIF at room temperature, determining the influence process parameters on material formability. The performed...

Abstract Laminated composites have so far received little attention as a potential material for gear drive applications. In the presented study, thermomechanical performance of newly developed type epoxy impregnated, autoclave-cured carbon fibre-reinforced polymer gear—running in pair with steel pinion—was analysed, using combination experimental and numerical approaches. The employed methods e...

A new type of materials, the backbone-thermoresponsive hyperbranched polyether, was successfully synthesized by proton-transfer polymerization of 1,4-butanediol diglycidyl ether and various triols, and the lower critical solution temperature (LCST) values can be readily adjusted from 19.0 to 40.3 degrees C by changing the hydrophilic/hydrophobic balance of BDE and triols.

T-cells, second only to macrophages, are often considered as the potential cells involved in debris-related failure of arthroplasty. Here, we assessed the effects of particulate wear debris on T-cells and inflammatory reactions. Blood samples from 25 donors were incubated with polyether-ether-ketone (PEEK) and cobalt-chromium-molybdenum (CoCrMo) particles generated by custom cryo-milling and pu...

Highly conductive and low vanadium permeable crosslinked sulfonated poly(ether ether ketone) (cSPEEK) membranes were prepared by electrophilic aromatic substitution for a Vanadium/Air Redox Flow Battery (Vanadium/Air-RFB) application. Membranes were synthesized from ethanol solution and crosslinked under different temperatures with 1,4-benzenedimethanol and ZnCl2 via the Friedel-Crafts crosslin...

In this study, a series of composites comprising polyether ether ketone (PEEK) and carbon fiber (CF)-reinforced polybenzoxazine for high-temperature friction materials vehicle brake applications were developed using compression molding technique. The objective research was to systematically investigate the thermal, mechanical (tensile flexural), tribological performance made from polybenzoxazin...
