Modelling of heat diffusion in composites

Composites structures are widely using in varied fields of industry, where it has to take into account changes of temperature or it is possibility of fire hazards. Heat transfer and fire conditions in composites are very often analysis issues nowadays. A large amount of research in area of modelling heat transfer and fire loading of composites has been performed for both experimental studies and modelling and simulation. The most common areas of analysis of thermal composite structures are: multiscale modelling of heat transfer, simultaneous fire and mechanical loading, fire involved failure and temperature distribution under fire and elevated temperature conditions. This paper presents analysis of heat transfer in composites with taking into account their shape and thickness. The models include a convection mode of heat transfer. The first composite plate is 10 cm wide by 10 cm tall with a thickness of 1 cm. The modified structure has also second part, smaller plate on top 5 cm wide by 5 cm in right corner. They made of glass/vinylester composite. The plates are heating in one, two and three directions. The results are shown in forms of contours of temperature distribution and thermal gradient. Comparison of results for the modelled structures shows differences in the shape and thickness of the analysed structure.
