    Identification Of The Tensile Properties Of Hybrid Composite Material By Artificial Neural Network
    (Oum-El-Bouaghi University, 2012) Singh, Vinay Kumar
    Composite materials are made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure. In the present work a silica-styrene-butadiene rubber hybrid composite material is developed with 1 and 2 wt% of nano sized silica particle and 0.25 to 1.5 wt% of styrene-butadiene rubber mixed in resin. Nonlinear relation between mechanical properties and filler material have been obtained. An artificial neural network (ANN) model with one hidden layer and two neurons seems to be approximate for the prediction of mechanical characteristic from the various weight percentage of filler material. Neural networks trained with the back-propagation algorithm are applied to predict the future values of tensile data with different percentage of constitute material. The influencing indicators of constituent percentage of composite material and strain rate are taken into consideration. The design and implementation of a neural network forecasting system is described that has been developed to estimate mechanical properties with different combination of constituent of developed composite material. The performance of the networks is evaluated by comparing them to the experimental data. The comparison shows that neural networks perform the conventional techniques with regard to the prediction quality.

    Tensile And Flexural Strengths Of Coconut Shell Particle & Coir Fibre Reinforced Composite
    (Oum-El-Bouaghi University, 2013) Bhaskar, Jitendra; Singh, Vinay Kumar
    This paper presents the tensile and flexural strengths of coconut shell particle and coir fibre reinforced wood composite. The composites material were fabricated by reinforcing coconut shell particle (size between 200-800µm) by 17- 28 wt% and coir fibre (2-5mm) by 2-3 wt% into epoxy matrix using open mould casting method. Microscopic investigations were done for estimating properties. Experimental results showed that ultimate strength, modulus of elasticity, % elongation decreases with wt% of shell particle. Ultimate strength and % elongation increases but modulus of elasticity decreases with the increase of coir wt%. Modulus of elasticity decreases with the reinforcement of shell particle and coir both. Flexural strength decreases with addition of coir fibre. The coconut shell particles and coir fibers are good reinforcing of 30 wt% materials to reduce the consumption of resin as well as utilizing waste natural material with maintaining the properties required for structural applications. The open mould casting method used has been proved to be easy way of composite material preparation.
