Verification of a two-dimensional infiltration model for the resin transfer molding process
… element model for the infiltration of a dry textile preform by an injected resin has been verified. The model, which is based on the finite element/control volume technique, determines the total infiltration time and the pressure increase at the mold inlet associated with the RTM process. …

Development of a Progressive Failure Finite Element Analysis For a Braided Composite Fuselage Frame
Short, J-section columns fabricated from a textile composite are tested in axial compression to study the modes of failure with and without local buckling occuring.The textile preform architecture is a 2x2, 2-D triaxial braid with a yarn layup of [0 deg 18k/+-64 deg 6k] 39.7% axial. The preform was …

Effects of fiber architecture and through-the-thickness stitching on permeability and compaction of textile preforms
… advanced and complex forms. Near net shape preforms have become popular, and techniques such as multi-axial warp knitting and 3-D braiding are used to accomplish this. Further, the combination of these preforms with manufacturing processes such as Resin Transfer Molding and Resin Film …

Verification of a Three-Dimensional Resin Film Infusion Process Simulation Model
… resin flow through an anisotropic carbon fiber preform, cure kinetics of the resin, and heat transfer within the preform/tool assembly. The computer model can predict the flow front location, resin pressure distribution, and thermal profiles in the modeled part. The formulation for the flow …
