The present work is aimed at investigating the mechanical and in vitro biological properties of polyphenylene ether ether sulfone (PPEES)/nanohydroxyapatite (nHA) composite fibers. Electrospinning was used to prepare nanofiber composite mats of PPEES/nHA with different weight percentages of the inorganic filler, nHA. The fabricated composites were characterized using Fourier transform infrared ...

Abstract In this review article, the joining of carbon fiber-reinforced polymer composite with metallic materials by using friction welding techniques was discussed and effects process parameters on weld properties were evaluated. Major involved in plunge depth (PD), dwell time, tool rotational speed. A successful joint poly laminate (CF-PPS)-metal formed an interlayer film additional polypheny...

although the solubility of oxygen in molten aluminum alloys is said to be negligible, the fresh surface of the melt oxidizes quickly in the air and an oxide film is formed on the melt surface. oxide-metal-oxide sandwich technique is a method for the study of short-time surface oxide films. in this research, air was blown at 0.5 atmosphere into the melts of al-1mg and al-6mg alloys by means of a...
