The study examined the effect of fillers on the mechanical properties of the recycled low density polyethylene composites under weathered condition with a view of managing the generation and disposal of plastic wastes. Discarded pure water sachets and fillers (glass and talc) were sourced and recycled. Recycled low density polyethylene (RLDPE) and preparation of RLDPE/glass, RLDPE/talc and RLDPE/glass/talc composites were carried out using a furnace at compositions of 0 – 40% in steps of 10% by weight. The mixtures were poured into hand-laid mould. The samples produced were exposed to sunlight for eight (8) weeks and their mechanical properties were studied. The results of mechanical tests revealed that tensile strength decreased with increasing filler loading while impact strength and hardness property increased marginally and considerably with increasing filler loading for all the composites respectively. The study concluded that glass and talc were able to reinforce recycled low density polyethylene under weathered condition.

This work compared the effect of fillers on the mechanical properties of recycled low-density polyethylene composites under non-weathered and weathered conditions. Pure water sachet wastes, glass wastes were sourced from dump-site at Obafemi Awolowo University, Ile-Ife, Nigeria, while the talc was sourced from Lagere, Ile-Ife, Nigeria. Recycling of plastic bags (low-density polyethylene) and the preparation of recycled low-density polyethylene (RLDPE)/glass, RLDPE/ talc and RLDPE/glass/talc composites were carried out using a furnace at compositions of 0 to 40% in steps of 10% by weight. The mixtures were then poured into hand-laid mould for tensile, impact and hardness tests. The samples were divided into two groups; one group was subjected to natural weathering conditions. The results of mechanical tests carried out were subjected to a paired t-test. The study concluded that there was no significant difference between the non-weathered and weathered samples. This implies that both talc and glass were able to reinforce recycled low density polyethylene (RLDPE) under both conditions and can help resist degradation.

A high modulus of elasticity is a distinctive feature of carbon fibres produced from mesophase pitch. In this work, we expand our previous study of pitch/linear low-density polyethylene blend fibres, increasing the concentration of the linear low-density polyethylene in the blend into the range of from 30 to 90 wt%. A scanning electron microscope study showed two distinct phases in the fibres: one linear low-density polyethylene, and the other pitch fibre. Unique morphologies of the blend were observed. They ranged from continuous microfibres of pitch embedded in linear low-density polyethylene (occurring at high concentrations of pitch) to a discontinuous region showing the presence of spherical pitch nodules (at high concentrations of linear low-density polyethylene). The corresponding mechanical properties—such as tensile strength, tensile modulus, and strain at failure—of different concentrations of linear low-density polyethylene in the pitch fibre were measured and are reported here. Thermogravimetric analysis was used to investigate how the increased linear low-density polyethylene content affected the thermal stability of linear low-density polyethylene/pitch fibres. It is shown that selecting appropriate linear low-density polyethylene concentrations is required, depending on the requirement of thermal stability and mechanical properties of the fibres. Our study offers new and useful guidance to the scientific community to help select the appropriate combinations of linear low-density polyethylene/pitch blend concentrations based on the required mechanical property and thermal stability of the fibres.
