Influence of microstructure and tribology properties on deep-dipping coating method of sappanwood (SW)/ polyvinyl alcohol (PVA)/ Polyethylene (PE)/ Aluminium nitride (AlN) natural fiber nanocomposite materials

The natural fiber nanocomposite materials employed in this study, which included sappanwood (SW), polyvinyl alcohol (PVA), polyethylene (PE), aluminum nitride (AlN), and epoxy resin (EP), were made by hand lay-up processes. Acryl Silane Coupling Agent (ASCA) was employed in the deep-dip coating method to enhance the tribology and microstructure of the natural fiber nano composite materials. For composite materials made of sappanwood and polyethylene, the resin microstructure was largely responsible for the observed homogeneous phase and hexagonal structure. The solid outer and secondary phases of the outer and inner surface layers of the EP-PE-SW-AlN composite materials were created using the silane coating process. Tensile properties of EP-PVA-SW-PE-AlN samples were reached at 42.8 MPa, and three-point bending tests were reached at 47.6 MPa. Furthermore, 597 °C was obtained for EP-PVA-SW-PE-AlN composite materials on TGA results. The average hardness value of (60) EP combined (10%) PVA, (10%) SW, (10%) PE, and (10%) AlN nano particle was highly present 98 (shore-D) throughout the silane coating process. Wear resistance and friction tests were performed on EP-PVA-SW-AlN, EP-PE-SW-AlN, and EP-PVA-SW-PE-AlN composite materials in order to improve the outer surface layers and interior composite structure. Dimples, micro voids, microscopic holes, and basket voids were seen on the fracture surfaces of each composite sample.
