Abstract:

The present work aims at developing a class of polymer composites consisting of thermoset polymer, i.e., epoxy as a matrix material with a micro-size filler material, i.e., hexagonal boron nitride (hBN) as a reinforcing material. A simple hand lay-up technique has fabricated a set of composite with varying filler loading. The effect of filler content on such fabricated samples' physical and mechanical properties is investigated and presented in this work. The various properties evaluated are density, void content, hardness, tensile strength, and the fabricated samples' compressive strength. The values obtained under controlled laboratory conditions are analyzed to identify their behavior. The experimental results found that the density of the composites increases with an increase in filler content. Also, voids are increased when filler in the epoxy matrix increases.
Further, hexagonal boron nitride inclusion in the epoxy matrix increases the composite's hardness and compressive strength. Against that, an increasing-decreasing trend is obtained when the tensile strength of the fabricated samples was analyzed. Tensile strength increases up to 10 wt. % of filler and a further increase in filler content reduces the tensile strength of the composites.
