Experimental investigation of physical properties of homogenous and functionally graded glass fiber reinforced vinyl-ester composites

- Nowadays, the industrial requirement of new materials continually evolving the innovation in the composite materials field. Functionally graded materials (FGMs) are specialized engineering materials with varying properties due to a geographic gradient in structure and composition. Numerous composites are being manufactured for specific purposes other than general features that are highly significant and valuable. This paper presents the findings on the physical characteristics of glass fiber reinforced vinyl-ester-based homogenous and functionally graded polymer composites followed by the fabrication of both types of composites. The findings showed that the void fraction and water absorption are found to be enhanced in the case of homogenous polymer composite than functionally graded polymer composite, and these characteristics were found to be increased with fiber loading.
