Mechanical strengthening effect by various forms and orientation of glass fibre reinforced isopthalic polyester polymer composite

Polyester resin enhances its mechanical property when it is reinforced with glass fibres. These glass fibre reinforced polyester composite were widely used in the marine applications. In this research work the polymer composite of three different glass fibres was reinforced with isopthalic polyester resin. By using the volume fraction of glass fibres and polyster resin as 60%-40%, 50%-50% & 40%-60%, various forms of glass fibers such as CSM 450, WRM 610, and COMBO MAT 910 laminates were prepared under each composition. Those Composites were fabricated using hand layup technique and subjected to post curing in a furnace of 80°C. The prepared laminates undergoes Barcol hardness test, tensile test, flexural test, water absorption and glass content test to investigate the best combination among the fabricated composites. Based upon the different mechanical property investigation, COMBO MAT 910 was termed as superior than all other laminates.
