摘要

Fiber reinforced polymer composites have gained substantial attention as engineering structural materials in automotive, marine and aircraft industry as well as in civil engineering applications. This is due to their outstanding mechanical properties, impact resistance, high durability and flexibility in design capabilities and light weight The present work describes the development and mechanical characterization of new polymer composites consisting of glass fiber reinforcement, epoxy resin and filler materials such as TiO2 and ZnS. The newly developed composites are characterized for their mechanical properties. The tests result have shown that higher the filler material volume percentage greater the strength for both TiO2 and ZnS filled glass epoxy composites, ZnS filled composite show more sustaining values than TiO2. The present work also describes the machining (drilling) of GFRP composites with the help of Step drill of three sets, with three different speeds. The work has been carried out by immersion of GFRP composites in sea water for 8hrs, 16hrs and 24hrs duration and performed drilling operation. Results revealed that 8-4 mm step drill showed better machining characteristic than the other two 12-8mm and 10-6 mm step drills. GFRP composite, with ZnS filler material soaked in sea water for 16hrs duration had better machining capability. The ZnS Filled GFRP composites had better performance than TiO2 filled GFRP Composites.
