A comparison of the unidirectional and radial in‐plane flow of fluids through woven composite reinforcements

摘要

AbstractThe in‐plane flow of fluids through dense fibrous woven reinforcements was studied to aid the development of constitutive models for use in simulations of composite fabrication by resin transfer molding. As a first part of this effort, both one‐dimensional and radial flow experiments were conducted with Newtonian fluids in several woven glass fabrics. Analysis of the one‐dimensional flow experiments shows that the two experimental techniques are often, but not always, consistent, and both techniques suggest a relationship between the physical structure of the reinforcement and the mathematical structure of the permeability tensor. Preform features at the laminar and interlaminar scales were hypothesized to influence the experimental re
