Compatibilizer Assistant SCF/ABS Composites with Improved Mechanical Properties Prepared by Fused Deposition Modeling

ABSTRACT A random terpolymer copolymer of styrene, acrylonitrile and glycidyl methacrylate (SAG) was used as compatibilizer to improve the interfacial adhesion of short carbon fiber (SCF)/acrylonitrile-butadiene-styrene (ABS) composites. Effects of SAG on the structural and mechanical properties of fused deposition modeling (FDM) printed composites were investigated. The results showed the addition of SAG could effectively improve the interfacial adhesion between SCF and ABS matrix, whereas slightly decrease average length of SCF and degrade the adhesion quality among deposited filaments. As a result, the tensile and flexural properties of FDM printed composites initially increased and then decreased with the SAG content. GRAPHICAL ABSTRACT
