EXPERIMENTAL INVESTIGATION OF HIGH FILLER LOADING OF SiO2 ON THE MECHANICAL AND DYNAMIC MECHANICAL ANALYSIS OF NATURAL PALF FIBRE-BASED HYBRID COMPOSITE

Abstract

This work aims to experimentally investigate high filler loading of  on the mechanical and dynamic mechanical analysis of natural PALF fibre-based hybrid composite. The compression moulding process was used to fabricate the composite. To achieve the aforementioned goals, the blends were made using 25 % PALF and varied weight proportions (3wt. %, 6wt. %, and 9 wt. %) of  nanoparticles. Tensile, bending, impact, interlaminar shear, shoreline D hardness, and dynamic mechanical analysis were all evaluated. SEM was used to examine the morphology of the materials, and an FTIR spectrometer was used to look for the presence of organic chemicals in fiber-reinforced composite materials. The findings show that adding 25 % PALF fiber and 6 %  nanoparticles (D-type) to the epoxy polymer improved the thermal and mechanical properties of the composites. It can be attributed to the improved interaction and homogeneous dispersion of the fillers and epoxy polymers. Moreover, the water uptake parameters of all samples were studied. The findings showed that the inclusion of reinforcements boosts the water uptake of the composite significantly. The initial deterioration rate of the -incorporated hybrids is almost the same, at about 400°C, which is considerably greater than that of the beginning breakdown temperatures of PALF (300°C), according to the thermography study. This might imply that the fiber and polymers form a stronger bond, reducing polymer movement and increasing the thermo-stability of the combination.
