    Composites has been an area of active research for the past several decades due to their lightweight and good mechanical properties. However, the aging of fiber reinforced composites is a major issue due to exposure of thermal, water and ultraviolet conditions. Continuous damage could bring about mechanical property degradation and damage at the interface. This is a comprehensive review on of aging effects in water, heat, ultraviolet etc. on composites and the changes in chemical, mechanical and interfacial properties, evaluated by nondestructive and micro-mechanic evaluations. It focuses particularly on composites with superior chemical, mechanical and interfacial properties, as well as good high resistance to aging, as these are considered to be important Structural materials. Types of composites and aging effects of aged composite by exposure to water, heat and ultraviolet radiation are explored. Based on these nondestructive and micro-mechanical evaluations methods are suggested to reduce the diverse ageing effects.
