Groundnut Shell

In-situ synthesis of high-density polyethylene (HDPE) reinforced groundnut shell particulate (GSP) composite with treated GSP within the range of 10-30 wt% at 10 wt% has been achieved. The adopted technique used in the production of the composite is melt mixing and compounding using two roll mills with a compression moulding machine. Properties such as hardness, tensile strength, impact energy and water absorption analysis were examined. The result revealed that addition of GSP increases the hardness value from 22.3 to 87 Hv. However, the tensile strength progressively decreased as the GSP increases in the HDPE. This trend arises due to the interaction between neighbouring reinforced particulate which appears to influence the matrix flow, thereby inducing embrittlement of the polymer matrix. It was also observed that water absorption rate steadily increased with an increase in the exposure time and the absorbed amount of water increases by increasing the wt% of the GSP. Analysing the obtained results, it was concluded that there were improvements in the hardness, tensile strength, impact energy and water absorption properties of the HDPE-GSP polymer composite when compared to unreinforced HDPE. On these premises, GSP was found as a promising reinforcement which can positively influence the HDPE properties of modern composites.

New Method

This paper studies the resistance of two high-density polyethylene geonets (manufactured with or without the additive Tinuvin 783) against thermo-oxidation. The materials were exposed to thermo-oxidation by two methods: oven-ageing tests at 100 °C and a new method developed by our research team. The damages suffered by the geonets were evaluated by tensile tests (determination of tensile strength, elongation at maximum load and toughness). Finally, the results obtained in the oven-ageing tests were compared with the results obtained by the new method.
