Composite laminates are fabricated by hand lay-up technique. Scanning Electro Microscope analysis on the composite materials is performed. A group of neat epoxy samples is fabricated for comparison purpose. Samples are analysed for their mechanical properties to establish an alkaline effect on sponge gourd. Indeed, a maximum value of strength and strain is observed over 20% filler loading for 24 hrs treated fibre composite.展开更多

Luffa aegyptiaca reinforced epoxy composites have been developed by hand lay-up method with Luffa fiber untreated and treated conditions for 12 Hrs and 24 Hrs in different filler loading as in 2:1 ratio (5%, 10%, 15%, 20% and 25%). The effects of filler loading on the moisture content, hardness, bulk density, apparent porosity, tensile and flexural properties were studied. In general, the treated Luffa fibre composite for 24 Hrs showed better improvement properties via addition of modified Luffa fibre as reinforcement. However, tensile and flexural properties improved continuously with increasing filler loading up to 20% but decreasing at 25% due to weak interfacial bonding for both untreated and treated composite. The favourable results were obtained at 20% for treated composite at 24 Hrs especially at tensile and flexural characteristics and are suitable for mechanical applications.展开更多
