Rheological Behavior of Composites Based on Carbon Fibers Recycled from Aircraft Waste

Abstract

Abstract. Rheological investigation of composite materials prepared from the recycled aircraft waste materials based on thermoset (epoxy/resin) matrix and long carbon fibers (CF) is presented with the aim of their utilization in consumer industry applications. The carbon fibers recovered via thermal process of pyrolysis were cut into about 150 ȝm length and melt mixed with thermoplastic matrices based on polypropylene (PP) and polyamide 6 (PA) and various modifiers -ethylene-ethyl acrylate-maleic anhydride (E-EA-MAH), polypropylene grafted maleic anhydride (PP-g-MA) and poly(styrene)-block-poly(ethylene-co-but-1-ene)-blockpoly(styrene) (SEBS). Rheological, electrical, mechanical, thermal and morphological results revealed the composites of recycled CF and PP/PP-g-MA as well as PA/E-EA-MAH to be the most promising candidates for new applications.
