Abstract

In this study, camphor soot was infused into coir fibers using osmosis technique. Further, modified coir fibers were reinforced in nylon 6 using the melt intercalation method by varying fiber content (0, 3, 6, 9 wt. %) to obtain camphor soot embedded coir fiber reinforced nylon composites (CSCFNCs). The presence of camphor soot infused coir fibers in nylon 6 matrix was confirmed through XRD peaks by forming a single peak for CSCFNCs compared to neat nylon 6. CSCFNCs were characterized for tensile strength, flexural strength, impact strength and density as per ASTM standards. Thermal behaviour of CSCFNCs were also investigated by TGA, DSC, MFI and DMA. Tensile strength, flexural strength and density of the CSCFNCs were enhanced compared to neat nylon 6. On the other hand, impact strength is reduced. MFI and tan δ values for CSCFNCs shows decreased trend due to constrained polymer movement. TGA analysis for CSCFNCs shows increased thermal stability, marginally. DSC analysis revealed two peaks at 228 °C and 468 °C corresponds to the melting point and degradation temperature of CSCFNCs respectively. DMA result shows the storage modulus of 700 MPa for neat nylon 6 and it is enhanced in the case of CSCFNCs. Maximum storage modulus was recorded for 6 wt. % CSCFNCs was 806 MPa. Creep study shows that 6 wt. % CSCFNCs has shown minimum impression depth 0.125 mm compared to neat nylon 6 0.212 mm. SEM reveals that the fibers are uniformly distributed in the matrix and experienced brittle fracture.
