The fabrication of composites is still based mainly on a trial and error procedure, because numerical simulation has not yet been applied to the development of control systems, which can correlate the main parameter values of the processes with the processing behavior and the final properties of the component. Understanding of this processing- structure- properties relationship and its implementation in industrial manufacturing procedures is the starting point to guarantee the high quality and reliability required for mass production. The aim of this work is to present some recent developments of the mathematical models that allow us to simulate the most important phenomena occurring during composites processing such as filament winding and RTM. In fact a real flexibility of production can be achieved by means of analytical models and correlated simulation software packages. This approach enables us to diversify the composite products economically and in a short time. Modelling a technological process means describing, through mathematical equations, the phenomena that occur during the process. Usually, achieving such an objective requires mass balance, force balance and energy balance equations. In this paper, several interesting applications of this method are presented. The strongly nonlinear character of the resulting system may be reduced by decoupling some of the phenomena and dependent variables into sub-models. First filament winding is divided into two major steps: winding and curing. The problem of winding simulation and trajectory optimization is undertaken with the study of fiber slippage during their lay- down on a general shape non-axisymmetric mandrel. Following this, the curing phase is modeled and simulated by developing four interrelated sub-models for the description of different phenomena. Some typical numerical results, giving an idea of the potential of the simulation code, are shown. Moreover, the RTM process description and numerical model is illustrated, and some relevant simulation results are presented. |
