Study on Permeability of 2.5D Woven Reinforcement Materials with Fractal Theory

Permeability is one of the key issues in the design of molds and in the molding process for composite manufacture.As a disordered fibrous assembly,2.5-dimension(2.5D)woven reinforcement materials have complex structure.It poses a challenge to the study of pore structure and the establishment of the theoretical permeability model.Toward addressing this problem,a powerful tool called fractal theory emerged.According to the analysis of 2.5D woven reinforcement material structure using fractal theory,it is foun...
