| Abstract | This study investigates the development of novel formulations for high temperature thermoplastic polymer composites by mixing either amorphous polyetherimide (PEI) or semicrystalline polyphenylene sulfide (PPS) matrices with incorporation of recycled carbon fibers (rCFs) and thermal black (TB) particles followed by processing them into filaments for Fused Filament Fabrication (FFF) 3D printing. Different formulations of composites were prepared using combination of rCF and TB in which rCF content is gradually replaced by TB to investigate the possible synergistic effect on the performance of the composites. The effect of rCF and TB contents on mechanical, rheological and thermal properties of composites were investigated. With the incorporation of 20 wt.% rCF, tensile modulus and strength of the composites enhanced up to 7 and 2 folds respectively. The incorporation of TB provides flexibility for the composite filaments while maintaining thermal and mechanical performance of the composites. The rheological characterization showed that melt viscosity of thermoplastic matrices are preserved even at high loadings of TB (up to 20 wt.%). The differential scanning calorimetry (DSC) characterization results showed that incorporation of TB shifted the crystallization temperature to lower degrees and hindered the crystal formation of semicrystalline PPS matrix which could possibly provide better layer adhesion of the printed parts. Moreover,the use of TB and rCF provides significant cost saving compared to virgin CF. The obtained results will allow us to understand the developed composites behavior and optimize the FFF printing parameters for better mechanical performance of the printed parts for aerospace applications |
