Carbon fiber reinforced composite material has been used as structural material for satellite. Recently, it has been used for large deployable reflector having high surface accuracy. Therefor, superior physical properties and its stability are required for the materials. Especially in space, environmental factors such as deteriorating radiation, thermal fluctuation, etc, exist. So the properties of material may not be preserved in the long time. Thus, it is important to predict the variation of characteristics on orbit that must be guaranteed and preserved in advance. In this research the variation of mechanical characteristic due to radiation on Carbon Fiber Reinforced Plastic for satellite usage is investigated by simulating space radiation environment. And then, the variation of mechanical characteristic on orbit is predicted.
