Abstract

Additive manufacturing (AM) is a novel technology for fabrication of the objects that may come in complex shapes. Fused filament fabrication (FFF) is one of the most widely used techniques to fabricate polymer composites with advantages such as cost efficiency, high speed, and simplicity. FFF technique suffers from mainly limited polymeric feedstock materials requiring suitable viscosity with limited functionality. Adding nanofillers to polymeric matrices to gain such multifunctional properties are alternative route for advanced applications. In here, polymer composites with thermally conductive fillers of BN and CNTs were explored in a semi-crystalline engineering thermoplastic polyether ether ketone (PEEK) matrix. The results presented that the thermal conductivity of neat PEEK composites increased from 0.32 W/mK to 1.56 W/mK with 40 wt.% BN fillers. Besides, the hybridization through 1 wt.% CNTs/30 wt.% BN filler addition enhanced thermal conductivity to 1.62 W/mK. Also, the composite filaments were successfully fabricated and 3D printed.
