Abstract
Aiming at the processes of heating and cooling in thermoforming, analyzed the transfer processes of composite film and established relevant mathematical model, then proposed a analytical calculation method of non-steady state temperature field of heat transfer of two-layers composite film. Calculated the solution of the differential equation by Laplace transform method, determined heat transfer parameter, then drew the curve of θ-t and θ-x by MATLAB. Put forward the general heat transfer function of two-layers composite film, applied it to design the time of heating and cooling and analyzed the temperature gradient, improved the thermoforming process and avoided the technological defects caused by heating and cooling.关键词
