Void Formation and Transport During Composite Laminate Processing: An Initial Model Framework

Source

The fabrication of a high-performance structural composite laminate, such as a 64-ply graphite/epoxy system, currently suffers from the occurrence of voids in the final part. This very complex process involves simultaneous heat, mass, and energy transfer along with chemical reaction in a multiphase system with time-dependent material properties and boundary conditions. This study presents an approach to modeling void formation, stabilization, and transport in this complex system; the approach utilizes dimensional analysis as well as an analogy between void transport in composites and removal of oil from sand by water flooding. The general framework of the model is presented and some initial results involving void stabilization by water vapor are described.
