Carbon fiber composites are preferred in transportation sector due to their high specific strength, modulus and resistance to corrosive environments. This paper reports on usage of Polyamide 6 in automobile exterior components by adding 30 % PP, PP-g-MA (Polypropylene-grafted-Maleic anhydride) as a compatibilizer and Short Carbon fibers (SCF) as reinforcement. The effect of compatibilizer on the tensile and impact properties of the composites has been studied. Composite with 3 phr PP-g-MA and 5 wt% SCF revealed highest tensile strength and only 10 % reduction in its value due to water saturation. Microstructure analysis and Grey relational analysis confirmed the experimental results.
Polyamide 6 (PA6)-based composites are of evolving interest due to its high strength, wear resistance, and barrier properties. The use of binary composites mostly with nanomaterial and glass fibers has been reviewed and presented in literature. However to obtain a balance of properties like stiffness, toughness, and strength along with cost reduction, ternary composites of PA6 have been designed. To achieve the balance, PA6 blend-based composites, with combination of microfiller/nanofiller or PA6 with combination micro-microfiller, PA6 with microfiller/nanofiller and fiber have been designed. The properties of PA6-based ternary hybrid composites depend on type of dispersed phase used, presence of compatibilizer, type of filler used (nanofiller or microfiller or fiber or hybrid) and combination of fillers used. However, a review in this direction is not available in literature. Here, in this study, an overall understanding of various fillers, dispersed phase, and their combinations can be understood along with the discussion on effect of these on tensile properties and
