Resin flow analysis with fiber preform deformation in through thickness direction during Compression Resin Transfer Molding

摘要: Abstract Resin flow during Compression Transfer Molding (CRTM) can be best described and analyzed in three phases. In the first phase, a gap is created by holding upper mold platen parallel to preform surface at fixed distance from it. The desired amount of resin injected into quickly flows primarily over preform. second phase initiates when injection discontinued moves down squeezing deforming until comes contact with Further closure final will compact thickness redistribute fill all empty spaces. This paper describes infusion. We assume that end one; there uniform layer covers entire surface. constrains through direction phase. model this as load on forces preform, simultaneously compacting constitutive equations describing compaction fabric well its permeability are included analysis. A numerical solution predicting front progression deformation developed experimentally verified. Non-dimensional analysis carried out role important non-dimensional parameters investigated identify their correlations for process optimization.
