摘要

Glass fibers are imparted as reinforcement material in polyester matrix and still it act as a preferred material for the marine industry. However, it is non-biodegradable material and involves high risk during processing. In this study, new monofilament fishnets were substituted as an alternative material for glass fiber in the polyester matrix. Mechanical properties of these composite specimens such as tensile strength, flexural strength and impact resistance in accordance with ASTM, were evaluated. SEM images of various composites revealed the relations between the reinforced fishnet/ glass fiber and woven roving with polyester matrix. The dynamic mechanical analysis of storage modulus, loss modulus and damping factor was carried out for the different composites, compatibility of these composites and its properties was studied. The results reveal that the fishnet based composites have appreciably higher mechanical properties. Furthermore, the glass fiber, woven roving and fishnet composite has more storage modulus and significant mechanical damping. A novel hybrid composite is recommended for large marine structures and it helps to sustain green environment.
