Development of Roofing Sheet Material Using Groundnut Shell Particles and Epoxy Resin as Composite Material

Abstract

The present work is on the development of roofing sheet material using groundnut shell particles and epoxy resin as composite material. Three different samples of roofing sheets “A”, “B” and “C” were prepared and produced from three different weight particle length sizes of 0.5mm, 1mm and 1.5mm at a weight ratio of 70:30 between epoxy and groundnut shell. The sample roofing sheets were cast manually and the rate of water absorption, tensile strength, impact and flexural strength due to bending and deflection were all experimentally evaluated. The sample specimen A with a particle length of 0.5mm have the lowest rate of water absorptivity value of 8.3% ,with the highest impact value of 29.65KJ/m2. Likewise sample B with a particle length of 1mm have the highest ductility and tensile strength of 2.356mm and 8.25N/mm2 respectively. The results revealed that Groundnut shell particles can be used as reinforcement for polymer matrix for the production of roofing sheets. Sample “A” was adopted in this work because of its excellence performance properties.
