摘要

This research of polypropylene hybrid nanocomposite made with 10 wt% abaca fiber (AF) and 1–5 wt% of nano silicon carbide (SiC) particles via hot compression moulding technique. For enhancing process compatibility and interface bonding between the matrix to reinforcement, the AF is involved in amino silane treatment after the sodium hydroxide process. Transmission electron microscope analysis revealed that the amino-treated AF/nano SiC particles are uniformly dispersed in the PP matrix, resulting in superior mechanical properties of composites. The effect of SiC concentration/AF on surface morphology and mechanical and moisture absorption behaviour is studied. PP composite with 10 wt% AF and 5 wt% SiC found higher impact toughness (4.3 kJ/m2), optimum Vickers hardness number (34 HV), improved tensile strength (66 MPa), better flexural strength (81 MPa), and reduced moisture absorption (2.9 % at 14 days processing). The optimum PP/10 wt% AF/5 wt% SiC nanoparticle hybrid nanocomposite is recommended for use in automotive cabinet components applications.
