Effect of Different Woven Linear Densities on the Properties of Polymer Composites

Abstract

In this study the effect of different linear densities of woven fabric and number of stacking laminate on the properties of woven fabric reinforced epoxy is investigated. In this study, woven fabrics with different linear densities of 50, 150, and 200 g/m² are used as reinforcements in epoxy resin. The thermal, flexural, and physical properties are evaluated. The results show that a further increase of the fiber content increases the flexural properties of the composites. For example, 200 g/m² exhibits higher fiber content than those of 150 and 50 g/m², this in turn results in higher flexural properties. As expected, the flexural properties are governed by the number of stacking laminate. Here, the flexural strength and modulus increase with the increasing number of ply used in the laminate system. It is also observed that the coefficient of thermal expansion (CTE) of the material decreases with the increase in fiber content.
