Popis: Enhance the properties of fiber-matrix interface by providing fiber coating is most important aspect in Fiber reinforced polymer matrix composites. To design polymer matrix composites with improved properties such as impact resistance, fatigue resistance, fracture toughness, endurance to viable greater performance and economic production for future applications like space structures, automotive components and other structural applications. The role of the coating material used as a bonding agent/interface layer for matrix and fiber has been studied to understand and make several useful conclusions on stress distribution pattern in various phases of cylindrical composite assembly under hygrothermal loading conditions which are prevailed especially in aerospace structures. Number of authors have reported the stress analysis of FRP Composites under hygrothermal conditions in the literature. Most of these predictions focused for metal matrix composites and a few are on three phase model on analytical analysis. This report involves analysis of cylindrical unidirectional composite assembly using four phase model exposed under hygrothermal conditions of loading using numerical technique as well as analytical approach. All the tabulations comparing the analytical and numerical predictions are made with suitable illustrations and graph representations indicating the effects of higher stresses, the impact of moisture penetration and hygrothermal loading etc.
