Abstract: Fiber reinforced plastics (FRP) consist of two major components: glass fiber and organic resin. Significant changes in FRP′s physical properties can be found as it goes through a series of physical and chemical evolution under heating conditions, which would further influence the internal temperature distribution of the material. Models regarding the changes in FRP′s physical properties can be set up by studying this process under heating. Using FRP samples, the cool-side temperature was recorded during arc-jet tests, which can be further compared with the results of the simulated calculations from the model. Since the calculated and the arc-jet results match each other very well, this model is suggested to be reliable for the engineering reality.

Key words: fiber reinforced plastics, heating conditions, physical properties, model setup
