Effect of Nano-Al3Mg2 Addition on the Microstructure of PEEK Nanocomposite Bulk Samples Consolidated from Mechanically Milled Powders

Abstract

In this investigation, the effect of the novel nano-Al3Mg2 particles addition on the microstructure of polyetheretherketone (PEEK) polymer matrix nanocomposite was studied. Bulk nanocomposite samples were fabricated by consolidation of ball milled composite powders through hot pressing method. The structural evolutions of mechanically milled powders as well as consolidated nanocomposites were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with an energy dispersive X-ray analyzer (EDX). The results showed that, although increasing the amount of β-Al3Mg2 nanoparticles up to 5 vol. % results in no chemical interaction, a low degree of PEEK crystallization, reduction in powder particle size, homogeneous distribution and well bonding of nanoparticles in the PEEK matrix but the tendency for agglomeration and porosity formation increases in comparison with 3 vol% of β-Al3Mg2.
