Evaluation of mechanical properties resulting from the addition of brass filings in recycled low-density polyethylene
Summary
This study evaluates how incorporating recycled plastic fibers affects the mechanical performance of composite materials. Researchers measured properties such as tensile strength, flexibility, and durability to assess whether recycled fibers can serve as viable reinforcement agents. The findings help determine the feasibility of using plastic waste streams in structural or engineering applications.
The growing concern about the environmental impacts resulting from the improper disposal of urban solid waste encourages the adoption of principles of reuse and the circular economy.With the technology currently available, it is feasible to reconcile this need with the practice of sustainable manufacturing, adding value to waste that would otherwise be destined for landfills or discarded in nature.The objective of this study is to evaluate the mechanical properties of recycled low-density polyethylene (LDPE) with different percentages of brass shavings, comparing the results with the material without any mixture.The aim is to explore alternatives that not only improve the mechanical properties of plastic materials but also potentially mitigate the environmental impact caused by their improper disposal.For this purpose, test specimens containing different levels of the metallic mixture were manufactured through pneumatic injection.At the end of this process, mechanical tests and hardness tests were carried out on the specimens.It was concluded that the addition of brass shavings was not mechanically advantageous for the specimens due to the poor interfacial adhesion between the matrix and the polymer matrix.
