Physical Properties of Polyester Composites Filled with Micro-sized Marble Stone Dust Particulates

Mechanical

This paper presents an experimental study on the physical behaviour of the polymer composites prepared with polyester as base matrix material and micro-sized marble stone dust particulates as a filler material. In the current investigation, the probability of using marble dust as a filler material in the polyester resin is explored to develop the composite body. Polyester-based composites are prepared by varying the content of marble dust up to 40 wt. % using the hand lay-up method. The properties investigated are density, void content and water absorption rate. From the study, it is observed that the inclusion of marble stone dust in the polyester resin increases the density along with the void content in the composite as a linear function of filler loading. It is further observed that the addition of marble stone dust does not cause a very high rate of water absorption as it is limited to a very low value even for a high filler loading.
