Abstract
Polypropylene composites reinforced with coir fibre and yam peel particulate were produced using compression moulding machine. Treated and untreated coir fibres were used; 1.5 M NaOH was used for the treated coir fibres. Yam peel was grouped into two, treated and untreated; the treated was modified using 1 M solution of NaOH and HCl in the proportion of 30% and 70%, respectively. The yam peel which was sun-dried for 14 days was pulverized and sieved to −45 µm. Samples were developed using treated and untreated reinforcements (TCF/YPP and UCF/YPP) at constant coir fibre proportion (15%) and varied amount of yam peel particulate (2, 4, 6, and 8 wt.%). The hybrid composite samples developed were probed for mechanical properties and thermal and wear behaviour. The level of particles agglomeration at the fibre-matrix interface was examined using scanning electron microscope. The results show that sample reinforced with treated 4 wt.% coir fibre and yam peel particulate had optimum mechanical properties. However, the thermal conductivity of composite samples increased with fibre addition. All composite samples developed had better resistance to abrasion when compared to the control sample.
Highlights
After energy generation distribution and conservation, one of the most important problems in the world is safeguarding of the environment
Improved interaction between matrix and reinforcement can be enhanced via chemical treatment to selectively depreciate the amount of the hemicellulose and lignin while improving the rough surface of the fibres. is treatment modifies the hydrophilic nature of the fibre to ensure good adhesion with the matrix which is highly hydrophilic [33]
Linear reduction was observed from 2 to −8 wt.% Coir fibre (CF)/yam peel particulate (YPP); this can be linked to the combined effect of coir fibre and particulate addition
Summary
After energy generation distribution and conservation, one of the most important problems in the world is safeguarding of the environment. New plans are being made every day in a bid to produce environmentally friendly materials which are not harmful to both humans and the environment at large Owing to this reason, researchers have diverted towards the utilization of natural fibres for the production of ecofriendly composites as a substitute over synthetic fibres being employed in the past. They are cheap, available in abundance, and renewable They possess the capacity to absorb carbon dioxide (CO2) from the atmosphere thereby improving the quality of oxygen available for human beings. These fibres do not give off deleterious gas and the equipment employed in processing them is not abraded, of which the opposite is the case for synthetic fibres [3, 4]
