Studies on unsaturated flow in dual-scale fiber fabrics
Fiber fabrics in liquid composite molding(LCM)can be recognized as a dual-scale structure.As sink theory developed,this unsaturated flow behavior has already been simulated successfully; however,most of simulated results based on a unit cell under ideal status,thus making results were not agreement with experiment.In this study,an experimental method to establish sink function was proposed.After compared the simulation results by this sink function,it shows high accuracy with the experimental data.Subsequently,the key influencing factors for unsaturated flow have been further investigated; results show that the filling time for unsaturated flow was much longer than saturated flow.In addition,the injection pressure and permeability were the key factors lead to unsaturated flow.
