Composites are an essential part of todays materials because they offer advantages such as low weight, corrosion resistance, high fatigue strength, faster assembly, etc. Composites are used as materials ranging from making aircraft structures to golf clubs, electronic packaging to medical equipment, and space vehicles to home building. Composites are generating curiosity and interest in students all over the world. This book describes the systematic study on composite material and R.V.E (Representative Volume Element). Then Simulation occurred on cotton/epoxy unidirectional composites with...
