Abstract
The soap stone is a mineral that is abundant in the Ouro Preto - MG region and it has an important role in local economy, since its major destination is in the local production of craftsmanship and vases and other decorating utensils. However, there’s a problem regarding the disposal of the waste material generated in those activities, that is usually thrown away without any control. Such materials can be harmful to the environment and to the health of local residents. Therefore, studies that evaluate other purposes for the waste are necessary. This work has as main objective to characterize the soap stone waste, and to manufacture polymer matrix composites using the waste as reinforcement and to evaluate the mechanical properties of these composites. The materials used in this work were high-density polyethylene (HDPE) as matrix and the waste of soap stone as the dispersed phase. The composites were made in three compositions: 90/10, 80/20 and 70/30. The characterization of the soap stone was done with x-ray diffraction. The tensile properties were used to characterize the mechanical behavior. The results were used to compare the properties obtained to those of the neat polymer used. The XRD revealed a monoclinic crystalline structure with crystalline peaks characteristic of the talc mineral. The composites had a more brittle mechanical behavior than the neat HDPE with a lower tensile strain at break, but presented higher tensile strength.
