Lecture
This lecture delves into the advanced composite manufacturing processes, focusing on infiltration and permeability phenomena in composite materials. The instructor discusses the modelling of fluid flow, heat transfer, and consolidation in various composite processing techniques. Examples of infiltration and simulation of resin transfer molding processes are presented, along with the importance of capillary phenomena and dynamic wetting effects. The lecture covers the parameters needed to solve the governing equations, such as resin viscosity and fiber bed permeability. Additionally, the discussion extends to stress equilibrium in the preform during processing and the validation of models for metal matrix composites. Various permeability prediction models and experimental techniques for measuring permeability are also explored.
