Effect of Compatibilizer Type on Enhancement in Glass Fiber Reinforced Polyketone and Polyketone/Polyamide 6 Composites
Abstract
This study investigates the influence of compatibilizer type on the mechanical performance of 30 wt% glass fiber-reinforced polyketone (PK) and PK/Polyamide 6 (PA6) composites. Two compatibilizers, ethylene terpolymer (C1) and maleic anhydride grafted polyethylene (C2), were employed to improve interfacial adhesion and phase dispersion. Results show that the use of C2 significantly enhances impact resistance and elongation at break without severely compromising stiffness. Compared to unmodified composites, C2-modified samples demonstrated up to 113% improvement in impact strength and over 160% increase in strain at break. These findings highlight the critical role of compatibilizer chemistry in adapt ductility and toughness in glass fiber-reinforced hybrid systems.
