Study of Manufacturing Process Optimization of Rigid Boards of LDPE/Al Composite Recycled

This study investigates the feasibility of using recycled low density polyethylene (LDPE) and aluminum of Tetra Pak, to manufacture experimental composite rigid board. The rigid board was made through a hot press. The effects of tensile, flexural, and water absorption process on LDPE/Al plastic composites were studied. Based on the findings in this work, it appears that recycled materials can be used to manufacture value-added panels without having any significant adverse influence on board properties. It was also found that the compounds of LDPE/Al are significantly affected by the effect of compaction pressure during processing, especially in the tensile strength and water absorption, were significant. The composite presents low water absorption, and acceptable tensile strength.
