In this paper, by employing ANSYS Workbench software and three-dimensional finite element simulation, the damage of fire insulated composite sandwich panels subjected to fire and impact loads is estimated. Also, an innovative method was introduced to protect composite sandwich panels with high exposure risk of fire and impact simultaneously. For this purpose, at first, the structure is subjected to impact of a projectile disk and the damage caused in the structure is estimated. Later, the structure is subjected to heat of the fire caused by hydrocarbon fuel. To demonstrate the validity and precision of the presented simulations, the obtained results are compared with the experimental and numerical results presented in the available literature. In all simulations, the properties of the laminated composite skins and core foam are temperature dependent. This research shows some practical results that can be helpful for design of composite sandwich panels with the risk of exposing fire and impact loads.
